Hi. I'm currently running a Debian 1.3 system, and I'm working on putting
together a Hamm system to replace it. I'm trying to get a ppp connection
running on an external modem plugged into COM2 of the Hamm system and I'm
having no luck.
First, I defined the connection and then 'pon' to start the connection.
No dice. /var/log/ppp.log contained the following lines:
pppd 2.3.5 started by root, uid 0
tcgetattr: input/output error (5)
Exit.
Ok, I went back a few steps. I pulled down the PPP-HowTo and slog
through the advice it has (which isn't 100% the same as the default Hamm
setup). I discovered that using Minicom, I didn't get any response to AT
commands sent to /dev/ttyS1.
I rebooted the system and use Lilo to boot MS-Dog. Kermit saw a modem on
COM2 and I was even able to use it to dial my ISP and transfer some more
stuff to my new system. So the modem/serial port/phone line *do* work.
Back to Linux (stopping by the BIOS setup on the way to note COM2's I/O
address and IRQ: 2f8, IRQ 3). I did a 'setserial /dev/ttyS1':
/dev/ttyS1, UART: 16550A, Port: 0x02f8, IRQ: 3
I searched the mailing lists, and everybody else who was having similar
problems was using Plug-n-Pray internal modems. No responses seemed to
apply to a built-in serial port.
So I'm stumped. I'm guessing it's a conflict of some kind, but it's a
little too subtle for my experience level.
Any help would be greatly appreciated.
Thanks in advance,
-packy
