Hi folks--
I'm trying to add a modem to a Dell Precision 410 running  debian
testing on top of Linux 2.2.6

One think I can't figure out is its device--/dev/ttyS??.

< other questions snipped>

I just finished setting up one of these (USR 5610) under a hd install of
Knoppix (= approx. Debian testing) the 2.4.26 kernel recognized the
 device at ttyS4 (which I already had symlinked with /dev/modem from
 a previous install) but the 2.6
kernel I wanted to use didn't find it there.
Tried all the lspci & setserial stuff. Ended up doing:

"dmesg | grep 'at'" which returns a bunch of lines where kernel recognizes
devices (device such and such AT such and such a  location)
Presuming it's finding it...
then if the ttS? exists... away you go. If not then do:
cd /dev; ./MAKEDEV ttyS?
(with ttyS? being whatever showed up in the dmesg | grep 'at' above)


Should work if the kernel is recognizing it at all, which it seems to be
from your post.

HTH. If not, apologies


BINGO! My initial installation only had /dev/ttyS0-3. Add that recipe to the troubleshooting FAQ!

It makes me wonder though, is there a utility to poll the h/w and update /dev appropriately?

Thanks!
