Figured it out: somehow permissions somewhere are getting
automatically reset, so 'sudo wvdial' is necessary. I'll just do it
that way, instead of worrying about the rest, I'm behind time on this job.
J.E.B.
Jonathan,
If the modem responds after it says
/dev/ttySM0 resource busy,
then the modem was occupied by something, maybe a certain process,
before you try to
# wvdial
what does
# ls /dev/ttySM0 -l
show?
The modem appears to work, since it shows up. What happens when you
try to dialout again? You are using Fedora 13 right? on an x86_64
bit machine? Since from the beginning you first tried ltmodem, then
got martian working. Now you believe that your modem might be bad?
BTW,
did you automate martian service? if you did, you may try
# service martian stop
# service martian restart
then
# wvdial
Also does your wvdial.conf have a line Carrier Check = no? in it?
Regards,
Antonio

Well, I might be trying a bad modem. It was working for a few trial
calls (I was given the voice number for the ISP, not the data), and then
stopped working. Now all I get is:
[scott@scottslinux ~]$ wvdial
--> WvDial: Internet dialer version 1.61

wvdial.log is empty, /var/log/messages has nothing about it. And yet
when I try to run 'wvdialconf' again it is successful (see below), and
does not modify my /etc/wvdial.conf.
Looks like bad hardware to me. What do you all think? I'll look for
another modem to use, buy one if I must -- any recommends?
