Subject: need help w/ Hayes ESP serial card and Linux
Date: Tue, 18 Jan 1994 16:39:52 GMT

I recently (ok, yesterday) purchased a Hayes 1-port ESP serial accelerator
"for windows". I guess I shouldn't be too surprised that I'm having
trouble with it in Linux, even though the card is supposed to be backward
compatible with the 16550,16450. I have the card set up as com1 (3F8) using
irq 9 and I am using setserial to tell this to Linux. (Linux does identify
the card as a 16550A upon boot up.) I was previously using my modem on
Com2, so I had to remake the /dev/modem file so it pointed to the right
spot. Using kermit, I can send commands to my modem. I can get it to dial
and everything, but I AM NOT GETTING ANY FEEDBACK FROM THE MODEM.

Is there some other program which tells Linux how to interact with
/dev/modem which I need to change, or is it just impossible to use this
card. I find it hard to believe that if I can send commands to my modem
through this port, that I can't recieve responses back through it. I have
already looked through the FAQ and have not found any help there.

Thanks for any and all help.

This is all true. 

But that doesn't mean that system administrators should just ignore or
blindly encourage the use of term. Term provides the ability for a
user to make his/her Linux system accessible over the internet,
including providing ftp and telnet access. This means that an
insecurely run Linux system, running term, is now a great back door
into your system.

Linux and term are great tools. Linux is the best thing to happen to
computing since they invented the 0 and the 1. But like any really
powerful tool, those who use it need to be educated on how to use it
safely. Otherwise they'll become a threat either to themselves or you.

        I am looking for the source for Xmosaic that will compile on a

from ncsa but it didn't include any of the header files that go in 
/usr/include.  I have gotten the binaries that go with linux, and it 
runs fine except I don't know how to make it do any kind of connection

   Well, at least with my version of tar ( currently 1.11.2 ) it does work.
   It does not, however, work with the '-z' ( compress ) flag.

You can or can't do multi-volume tape backups depending on the
- Linux version,
- your tape drive, and
- the backup program.

Linux before version 0.99.15 (which is not out yet) has a bug in
detection of end-of-medium. This will be corrected in 0.99.15.

Some tape drives will execute the commands necessary for multi-volume
backup. For instance, tar wants to back over one record when reaching
EOM and write a record telling that the backup is continued. Some drives
will not start writing between records (my Wangtek 5525ES is like this).

Multi-volume support may or may not be compiled into the archiving
program. I once had a tar which did not include it.

Subject: HIGH load on CPU while using rz!  Why?
Date: 18 Jan 94 18:16:20 GMT


        I have a 386sx/25 with 8mb ram.  I have a Supra 14.4 internal modem.
When I download files, my CPU load goes way up.  (Around .8 to 1.7 or so)
It hogs the CPU so bad that I get lag trying to do anything else on another
console.  One thing I can't figure out is that when I boot my system, it sees
a 16450 UART on COM2 (where my modem is).  I have two COM ports on my IDE 
card, but I have COM2 diabled on it.  ( The IDE card has 16450s)  I tried 
recompiling my kernel hoping that it would see the 16550 on my modem, but 
that didn't work.  Any ideas?  (Please email responses) Thanks in advance!

I am not sure, but I'd say no.

To you all three, ftp to sunsite.unc.edu and get the file ftape.HOWTO in

   I have heard of someone getting a large IDE drive and he claims

A way to specify the HD geometry of your IDE drive to Linux without

The following is the relevant comments in config.h.

Hope this helps,

 NOTE: ctl is 0 for all drives with heads<=8, and ctl=8 for drives

 If you want the BIOS to tell what kind of drive you have, just
 leave HD_TYPE undefined. This is the normal thing to do.
