INTRODUCTION 
  
This file is designed to answer some of the most frequently asked  
questions regarding Graph-TI and Calc-TI.  If you have a question, you  
should first check to see if it is answered here, rather than posting  
the question to the Newsgroups or to the lists. 
  
If you have any suggestions, corrections, or questions regarding this  
FAQ, or regarding any aspect of Graph-TI or Calc-TI, please send them  
to: 
     ti-cares@ti.com. 
  
IMPORTANT INTERNET ADDRESSES 
  
There are several addresses which are associated with the Graph-TI and  
Calc-TI lists and the Graph-TI archive.  It is important that you not  
mix these up, or you may end up sending list server commands to the  
archive or even posting them to the list.  The following addresses are  
used to access the lists and the archive. 
 
Newsgroups 
   Graph-TI Newsgroup:    bit.listserv.graph-TI 
   Calc-TI Newsgroup:     	bit.listserv.calc-ti    
 
Mailing lists 
   list server:   	majordomo@lists.ppp.ti.com (for subscription requests) 
   Graph-TI list: 	graph-ti@lists.ppp.ti.com  (for posting to Graph-TI) 
   Calc-TI list:  	calc-ti@lists.ppp.ti.com   (for posting to Calc-TI) 
 
Graph-TI archive 
   via e-mail:          	mailserv@archive.ppp.ti.com 
   via anonymous ftp:   	archive.ppp.ti.com (directory pub/graph-ti) 
   via gopher:          	archive.ppp.ti.com (login as "gopher") 
 
Commands relating to the lists like "subscribe" and "unsubscribe" in  
general should be sent to the list server.  Messages which you want to  
post to all Graph-TI list subscribers should be sent to the Graph-TI  
list (or should be posted to the Graph-TI Newsgroup).  Messages which  
you want to post to all Calc-TI list subscribers should be sent to the  
Calc-TI list (or should be posted to the Calc-TI Newsgroup).  Commands  
relating to the Graph-TI archive should be sent to the Graph-TI archive. 
 
Questions or comments of any kind can be sent to 
 
     ti-cares@ti.com. 
 
======================================================================== 
Question:   What are Graph-TI and Calc-TI? 
  
Graph-TI was created by Professor Bert Waits of Ohio State University  
and by Texas Instruments to provide a forum for free exchange of  
educational information regarding the Texas Instruments TI-80,TI-81, TI-82,  
and TI-85 calculators,  CBL (Calculator Based Labratories) and Cabri Geometry.   
It has various forms: the Newsgroup, the list, and the archive.  The Newsgroup and the list  
allow subscribers from around the world to share information with each  
other relating to education and the TI calculators.  The archive is a  
collection of programs and documents for the TI calculators; anyone may  
submit programs to the archive or download programs from it. 
  
ONLY EDUCATIONAL TOPICS ARE ACCEPTABLE ON GRAPH-TI.  Please do not post  
anything to Graph-TI unless it is related to education. 
 
Calc-TI was created as a forum for discussion of topic related to all  
Texas Instruments calculators, but not necessarily related to education.   
It is in many ways similar to Graph-TI, except that all topics related  
to all Texas Instruments calculators are acceptable on Calc-TI.   
Calc-TI, like Graph-TI, has two forms:  a list and a Newsgroup.  Note,  
however, that the Graph-TI archive serves both Graph-TI and Calc-TI.   
There is no Calc-TI archive, and non-educational materials are allowed 
in the archive. 
  
The Newsgroups and the lists contain exactly the same information.  Any  
information sent to one of the lists is automatically posted to the  
corresponding Newsgroup, and vice versa.  Therefore, there is no reason  
to subscribe both to a list and its Newsgroup.  If you are able to  
subscribe to a Newsgroup, you should probably do so, since a Newsgroup  
has many advantages over a list.   
  
If you are interested only in educational topic, you should subscribe  
only to Graph-TI.  If you are interested only in non-educational topic,  
you should subscribe to Calc-TI.  If you are interested in both  
educational and non-educational topics, you may want to subscribe to  
both Graph-TI and Calc-TI.  
======================================================================== 
 
Question:   What are the Graph-TI and Calc-TI lists? 
  
The Graph-TI and Calc-TI lists are automated e-mail mailing lists.   
Postings to the Graph-TI list are sent directly to the e-mail address of  
each person who is subscribed to the Graph-TI list, and postings to the  
Calc-TI list are sent to all Calc-TI list subscribers. 
  
If you have access to Internent news, you probably would prefer to use  
the Newsgroups, rather than the lists.  See "What are the Graph-TI and  
Calc-TI Newsgroups?" for more information. 
  
======================================================================== 
Question:   How do I subscribe to the Graph-TI or Calc-TI list? 
 
To subscribe to the Graph-TI or Calc-TI list, send an e-mail message to  
majordomo@lists.ppp.ti.com.  The message should contain only the  
following line: 
 
     SUBSCRIBE {listname} 
 
You should replace {listname} in the above line by GRAPH-TI or CALC-TI,  
depending on which list you want to subscribe to. The commands are not  
case-sensitive so you may mix upper and lower case letters.  Do not  
include the brackets.  Example:   you would subscribe to the Graph-TI  
list by sending the following line in an e-mail message to  
majordomo@lists.ppp.ti.com: 
 
     SUBSCRIBE GRAPH-TI 
 
======================================================================== 
Question:   How do I remove myself from the Graph-TI or Calc-TI list? 
 
To remove yourself from the Graph-TI or Calc-TI list (to "unsubscribe"),  
send an e-mail message to majordomo@lists.ppp.ti.com.  The message  
should contain only the following line: 
 
     UNSUBSCRIBE {listname} 
 
You should replace {listname} in the above line by GRAPH-TI or CALC-TI,  
depending on which list you want to remove yourself from.  Do not  
include the brackets.  Example:  to remove yourself from the Graph-TI  
list, send the  following line in an e-mail message to  
majordomo@lists.ppp.ti.com: 
 
     UNSUBSCRIBE GRAPH-TI 
 
This should be sent from the same e-mail address used when you  
subscribed. If your e-mail address has changed since you subscribed, and  
you are no longer able to send mail from the original address, please  
send mail to: 
 
ti-cares@ti.com explaining your situation. 
 
======================================================================== 
Question:   I can't seem to unsubscribe from the Graph-TI or Calc-TI  
list.  What do I do? 
  
The list server keeps track of your subscription by your e-mail address,  
not by your name.  If your e-mail address changes slightly (as e-mail  
addresses do occasionally), the list server will no longer recognize you  
as the same person who subscribed originally, and will not let you  
unsubscribe.  Note, however, that in such a situation the mail from the  
list will almost certainly continue to be forwarded from your old  
address to your new address, so small changes in your address will not  
interfere with your subscription unless you try to unsubscribe. 
  
If this happens to you, please send mail to ti-cares@.ti.com.  They 
will remove you from the list. 
  
======================================================================== 
Question:   How do I post a message to the Graph-TI or Calc-TI list? 
  
To post a message to the Graph-TI list, send an e-mail message to Graph- 
TI@lists.ppp.ti.com.  To post a message to the Calc-TI list, send an e- 
mail message to Calc-TI@lists.ppp.ti.com.  Your message will be posted  
to the list (copies will be sent to all list subscribers). 
  
As a courtesy to the readers of your posting, and to reduce private  
messages on the list, your message should AWLAYS include the following: 
  
     * Your Name 
     * Your e-mail address 
     * Postal mailing address if you are requesting that something be  
       sent to you through postal mail. 
  
Postings to either list should relate to Texas Instruments graphing  
calculators.  Postings to Graph-TI should also relate to education. 
 
======================================================================== 
Question:   How do I reply to a posting so my reply will be sent to  
everyone on the list? 
  
Send your posts to Graph-TI@lists.ppp.ti.com or Calc-TI@lists.ppp.ti.com  
to ensure they get to the list. Simply choosing the reply feature on  
most mail readers will not work because postings from the list come from  
the list owner's address rather that the list address itself. 
======================================================================== 
Question:   How do I reply to a posting so my reply will be sent only to  
the author of the post? 
  
To reply to the author of a post, you need to copy the address of the  
poster as given by the poster. The header information will not contain  
the posters address.  This is why it is important to include your e-mail  
address in your message whenever you post. Most people include it in the  
salutations at the end of their message. 
 
======================================================================== 
Question:   How do I get "back issues" of Graph-TI or Calc-TI? 
  
The archive files will be placed in our anonymous FTP tree with 
the path names: 
 
     /ftp/pub/list_archives/calc-ti.archive 
     /ftp/pub/list_archives/graph-ti.archive 
 
The file names will be: 
 
     calc-ti.yymm 
     graph-ti.yymm 
 
Messages will be grouped into these files on a monthly basis. 
 
Refer to the section on accessing the archives below for details on  
accesssing these addresses. 
======================================================================== 
Question:   How do I find out about some of the list server's other  
capabilities? 
  
The list server understands more commands than the few (SUBSCRIBE and  
UNSUBSCRIBE) described above.  It is possible to get a list of  
subscribers to either list, and to do other things.  If you want more  
information about the extended capabilities of the list server, send an  
e-mail message to majordomo@lists.ppp.ti.com.  The message should  
contain only the word HELP. 
  
======================================================================== 
 
Question:   What are the Graph-TI and Calc-TI Newsgroups? 
  
The Graph-TI and Calc-TI Newsgroups are Internet Newsgroups.  The name  
of the Graph-TI Newsgroup is bit.listserv.graph-ti.  The name of the  
Calc-TI Newsgroup is bit.listserv.calc-ti.  Subscribers to the  
Newsgroups use a program called a news reader to read messages on the  
Newsgroups and to post messages to Graph-TI or Calc-TI. 
  
======================================================================== 
Question:   How do I subscribe to the Graph-TI or Calc-TI Newsgroup? 
  
The exact procedure varies among news readers and systems.  In general,  
you will want to select bit.listserv.graph-ti (for Graph-TI) or  
bit.listserv.calc-ti (for Calc-TI) and tell the news reader to subscribe  
you. 
  
For example, if you are using the UNIX news reader trn and you want to 
subscribe to the Graph-TI Newsgroup, you should type 
  
     g bit.listserv.graph-ti 
  
to select bit.listserv.graph-ti.  trn will note that you are not yet  
subscribed to bit.listserv.graph-ti, and will ask you if you want to  
subscribe.  Hit y and trn will subscribe you.  The procedure for  
subscribing to the Calc-TI Newsgroup is the same, except you should type 
  
     g bit.listserv.calc-ti 
  
======================================================================== 
Question:   How do I unsubscribe from the Graph-TI or Calc-TI Newsgroup? 
  
The exact procedure varies among news readers and systems.  In general,  
you will want to select bit.listserv.graph-ti (for Graph-TI) or  
bit.listserv.calc-ti (for Calc-TI) and tell the news reader to  
unsubscribe you. 
  
For example, if you are using the UNIX news reader trn and you want to  
unsubscribe from the Graph-TI Newsgroup, you should type 
  
     g bit.listserv.graph-ti 
  
to select bit.listserv.graph-ti, and then type u to unsubscribe from it. 
 
The procedure for unsubscribing from the Calc-TI Newsgroup is the same, 
except you should type 
  
     g bit.listserv.calc-ti 
  
======================================================================== 
Question:   How do I read messages posted to the Graph-TI or Calc-TI  
Newsgroups? 
  
The exact procedure varies among news readers and systems.  In general,  
you will want to select bit.listserv.graph-ti (for Graph-TI) or  
bit.listserv.calc-ti (for Calc-TI) and tell the news reader to show you  
the messages.  Some news readers will immediately start showing you the  
messages, one after the other.  Others will first show you a list of the  
topics of the messages, and will allow you to select by topic those  
messages which you wish to read. 
  
For example, if you are using the UNIX news reader trn and you want to  
read the messages posted to the Graph-TI Newsgroup, you should type  
 
     g bit.listserv.graph-ti 
  
to select bit.listserv.graph-ti, and then hit return to get a list of  
topics (threads).  You can select those threads you want to read by  
pressing the key corresponding to the letter next to them.  When you're  
done, hit return and trn will show you all the messages in the threads  
you selected.  The procedure for reading messages posted to the Calc-TI  
Newsgroup is the same, except you should type 
  
     g bit.listserv.calc-ti 
  
======================================================================== 
Question:   How do I post a message to the Graph-TI or Calc-TI 
newsgroups? 
  
The exact procedure varies among news readers and systems.  In general,  
you will want to select bit.listserv.graph-ti (for Graph-TI) or  
bit.listserv.calc-ti (for Calc-TI) and tell the news reader to post a  
message.  You will then type the message, and when you+re done the news  
reader will post it. 
  
For example, if you are using the UNIX news reader trn and you want to  
post a message to the Graph-TI Newsgroup, you should type 
  
     g bit.listserv.graph-ti 
  
to select bit.listserv.graph-ti, and then hit return to get a list of  
topics.  Use the instructions above to read the message you are  
responding to (or any existing message of you are not responding to  
anyone), and then press f to follow-up to the message.  Hit y and return  
if you are posting a message unrelated to the one you read, or n if you  
are posting a message which is a follow-up to the message you viewed.   
Type the subject of the post and press return, press return at the  
Distribution prompt, press y and return if you really want to post,  
press return unless you want to include a separate file, and type your  
message, leaving a line between your message and the news header.  When  
you are done, save the file and exit (using whatever commands your  
editor uses; for emacs it would be control-x control-s control-x  
control-c).  Press s to send the message, and trn will post it for you.   
The procedure for posting messages to the Calc-TI Newsgroup is the same,  
except you should type 
  
     g bit.listserv.calc-ti 
 
As a courtesy to the readers of your posting, and to reduce private  
messages on the list, your message should AWLAYS include the following: 
 
     * Your Name 
     * Your e-mail address 
     * Postal mailing address if you are requesting that something be  
       sent to you through postal mail. 
 
Postings to Graph-TI should relate to Texas Instruments graphing  
calculators and their use in education education.  Postings to Calc-TI  
should relate to any Texas Instruments calculators, and not necessarily 
related to educational issues. 
======================================================================== 
Question:   How do I reply by e-mail to the author of a post? 
  
The exact procedure varies among news readers and systems.  In general,  
you will want to select bit.listserv.graph-ti and tell the news reader  
to reply by e-mail to the author.  You will then type the message, and  
when you're done the news reader will mail it. 
  
For example, if you are using the UNIX news reader trn, you should type 
  
     g bit.listserv.graph-ti 
  
To select bit.listserv.graph-ti, and then hit return to get a list of  
topics.  Use the instructions above to read the message you are replying  
to, and then press r to reply to the message.  Hit return (if you do not  
want to include a file from your directory), and then type your message  
below the header information, leaving a blank line between the header  
and your message.  When you are done, save the file and exit (using  
whatever commands your editor uses; for emacs it would be control+x  
control+s control+x control+c).  Press s to send the message, and trn  
will post it for you.  The procedure for replying to a post to the Calc- 
TI Newsgroup is the same, except you should type 
  
     g bit.listserv.calc-ti 
  
IMPORTANT:  Due to peculiarities in the way the Graph-TI and Calc-TI  
handle e-mail replies, some news readers on some machines may not be  
able to automatically reply directly to the author; instead, such  
replies will be posted sent to everyone on Graph-TI.  To identify this  
problem, look at the e-mail header while you're typing a reply.  If the  
first line of the header reads  
 
"To:  graph-ti@lists.ppp.ti.com" then you must change that line to  
specify the author's e-mail address.  For instance, if the author's  
e-mail address were janedoe@univ.edu, you would change the first line  
of the header to "To:  janedoe@univ.edu". 
 
 
Question:   What is the Graph-TI archive? 
  
The Graph-TI archive is a collection of programs and documents for the TI-80,  
TI-81, TI-82, TI-85 calculators, and associated products.  Anyone may  
download these programs, and anyone may submit programs to the archive.   
The archive, which is located at archive.ppp.ti.com, can be accessed  
through e-mail, anonymous ftp, or gopher. 
  
======================================================================== 
Question:   How do I access the Graph-TI archive through e-mail? 
  
The Graph-TI archive can be accessed by sending commands through e-mail.  
Such commands should be sent to mailserv@archive.ppp.ti.com.  For a list  
of all available commands, send an e-mail message to  
mailserv@archive.ppp.ti.com.  The message should contain only the word  
HELP.  A help file will be mailed to you.  
 
For convenience, part of the help file is listed below: 
  
LS/DIR - Produce a directory content listing for each directory  
specified. 
A fully qualified pathname is required for each desired directory  
listing. 
Each directory specified must exist on the DS server. 
 
     Examples:  ls /ftp/pub/graph-ti 
                ls /ftp/pub/graph-ti/misc 
                dir /ftp/pub/graph-ti/ti-85 
 
Note: The beginning (root) of the public file space is the /ftp  
directory.  The anonymous ftp login changes the top of the file system  
to /ftp.  This results in implicitly prepending /ftp to all fully  
qualified file specifications.  The mail server AWLAYS checks fully  
qualified file specifications for the leading /ftp.  If it is not found, 
it is prepended by the mail server.  This allows an ftp user to give a  
tip on retrieving a file to a mail server user and have the mail server 
find and send the file.  The examples in this user guide use both 
forms. 
 
FILE - Request a particular file be transferred by e-mail.  It requires  
a fully qualified pathname for each desired file.  The file(s) specified  
must be in the public file space on the DS server.  The command fails if  
the specified file does not exist.  This is the best command for  
requesting files since there is no ambiguity when fully qualified  
pathnames are used. 
 
     Examples:  file /ftp/pub/graph-ti/README. 
                file /ftp/pub/graph-ti/ti-85/anov1.85  
======================================================================== 
Question:   How do I submit a program to the Graph-TI archive? 
  
To submit a program to the archive, you should mail it to  
ti-cares@ti.com. TI will verify that the program contains an  
absctract, documentation, ascii equivalent of the program, and the  
uuencoded program itself.  If any of the above sections are missing the  
program will be returned to you.  New programs will be posted to the  
archive on a weekly basis so if you don't see your program in the  
archive immediately, wait another week. 
 
The program must be uuencoded, and you must include the manual and the  
abstract.  The precise format for this command is as follows: 
  
  {abstract} 
  ----begin documentation---- 
  {documentation} 
  ----begin ascii---- 
  {text equivalent of program} 
  ----begin uue---- 
  {uuencoded program} 
  
The ascii section (from ----begin ascii---- to ----begin uue----) is  
optional, but all three ----begin xxx---- lines must be present. 
 
======================================================================== 
Question:   How do I access the Graph-TI archive through ftp? 
  
The Graph-TI archive accepts anonymous ftp logins.  You can access the  
archive through ftp by connecting to archive.ppp.ti.com and logging in  
with username "anonymous".  You should type your e-mail address as the  
password.  The programs are located in the pub/graph-ti directory. Don't  
be alarmed if you encounter a disclaimer from AT&T, as they are  
running the archive for TI. 
  
======================================================================== 
Question:   How do I access the Graph-TI archive through gopher? 
  
There are two ways to connect to the Graph-TI archive with gopher. If  
you are running a gopher client, then point it to archive.ppp.ti.com.   
Select the menus 
 
     4. InterNIC Directory and Database Services (AT&T)/ 
        4. InterNIC Database Services (Public Databases)/ 
           9. Graph-TI Program Archive/  
 
If you do not have a gopher client, then you may connect to the Graph-TI  
archive with a remote gopher client. You must telnet to  
archive.ppp.ti.com and login as "gopher" (in all lower case letters,  
without the quotation marks). Then select the same menus as indicated  
above.  To retrieve a file, look at the file, type q to quit browsing it,  
and then enter m to mail the file to your e-mail address. 
 
======================================================================== 
Question:   How do I transfer an archive program to my calculator? 
  
To transfer an archive program to your calculator you need the TI-GRAPH  
LINK software, available from Texas Instruments.  TI-GRAPH LINK runs on  
either IBM-compatible PC or Macintosh computers. 
  
Archive programs are uuencoded, so you need to first run UUD20.EXE to  
uudecode the archive file before transferring it with TI-GRAPH LINK.  
UUD20.EXE and more detailed instructions are available on the disk  
included with the TI-GRAPH LINK software. 
  
If you do not have the TI-GRAPH LINK software, you may be able to  
enter a program manually by looking at the ASCII section of the  
files, if it exists.
