There are two basic ways to transfer data to and from this system. One
way is the STRAIGHT ASCII transfer. This simply means that the data to
be sent is sent over the phone line looking just like it does on your
disk file. No error checking of any kind is done and data can be mod-
fied by a bad phone connection. You may send or receive BASIC program
files IF they were saved with the "A" option (to make them ASCII). 

The other method used on this system for file transfer is the CP/M
method commonly referred to as the MODEM/XMODEM protocol, as orginally
defined by Ward Christensen. This transfer method does error checking
to ensure that the data being sent or received is intact. The file
checking method uses a checksum of the data bytes sent to verify
correctness. This is the preferred method if you have a program on
your system to receive or sent with this method.

UPLOAD means that you want to sent a file TO this system. You CANNOT
use a name that already exists on the disk. A check is made and you will be
notified if that condition occurs. You will be asked for the file name
and a brief description of the file (30 characters maximum). This data is
placed in the list of files available to transfer so that other users
may access and transfer it to their system. The list is maintained in a
LAST IN-FIRST OUT order, with the file name, description, size, approximate
transfer time, and date added to the system.
Send BASIC programs in ASCII format only, so they can be downloaded by
everybody. To do this, save your program on your system prior to the file
transfer by saying SAVE"MYPROG",A.

DOWNLOAD means that you want to transfer a file FROM this system to yours.
You will asked for the file name (be sure to use the FULL FILE NAME). A
check will be made to ensure that the name given does really exist.

To CANCEL the MODEM/XMODEM transfer (either UPLOAD or DOWNLOAD), type a
CONTROL-X.

To CANCEL the ASCII file transfer (download), type a CONTROL-K.
To CANCEL the ASCII file transfer (upload), stop the transmission of data
from your end, and then press then escape key. 
                           
ASCII UPLOAD allows you to send an ASCII file to this system. You terminate
the transfer by pressing your ESCAPE key. When an ESCAPE is received, the
bulletin board will save your file and make it available to other users.
There is NO DATA echo from the BBS during an ASCII upload from your system.
