[NTLUG:Discuss] Modem

[Paul Ingendorf]

I don't know if I would go through all that other stuff, you start off
simple then you get out the propeller hat and try and tweak what is under
the hood.  I would just create the symlink to /dev/modem and see if it is
picked up if not try getting minicom and seeing if you can run AT commands
on /dev/ttyS00.  Try typing ATZ.  Chances are the modem is installed or you
have other problems.  First thing it to make sure it really isn't there,
then you go about figuring out what needs to be tweaked to get it back.

O.K. In order

Terry - On the side of the box it says "Controller-based" and on the
end, under system requirements, it says "Linux (Kernel 2.3 and higher)".
I am pretty sure that means it is a hardware modem. A possible problem
is my Kernel appears to be 2.2.


Ralph - The distro is Debian 3.0 R4I3 and the DE is Gnome. It does not
appear to have kppp.
Yes, and I was also a member of the Chicago 7 :) LOL


Paul - I ran the 2 commands you suggested and got:

dmesg | grep tty

ttyS00 at 0x3f8 (irq=4) is a 16550A

lspci -vv

Serial Controller: USRobotics/3COM 56K FaxModem Model 5610 (rev 01)
(prog-if 02[16550])
Control: I/O+ Mem- Busmaster- SpecCycle- MemWINV- VGASnoop- ParErr-

Status: cap+ 66Mhs- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort-
<TAbort- <Mabort- >SERR- <PERR-
Interupt: pinA routed to IRQ0

D3cold+>
Status: D0 PME- Enable- Dsel=0 PSCALE=2 PME-

That "ttyS00" looks a little funny. Shouldn't there be just one 0?


Alvin - Based on the results I got from Paul's suggestions it appears I
should try:

/sbin/setserial /dev/modem uart 16550A port 0x3f8 irq 4

and then:

ln -s /dev/ttyS00 /dev/modem


I will give this a try and see what happens.
