trouble initializing my modems sometimes

Post by pluc.. » Sat, 24 Jul 1999 04:00:00

I've got a problem with my external modems under linux.
I know the modems are all right (running Win98, I can use them).
I have also been able to use them under linux, and they were working
Yesterday, I installed a second modem (a USR one). The modem was
present, but minicom couldn't initialize it. I tried to change the
settings and got no results. Eventually, I turned the computer off,
changed the modem's serial port, and suddenly it worked perfectly!
However, after the next reboot, the problem was back. This is annoying,
but acceptable as I only want my modem to be dialed in under linux (and
when the modem's dialed in, everything's fine).
Meanwhile, I took my oldest modem (an Olitec one) to another PC, running
the same version of Linux (Mandrake 6.0). The Olitec had never got any
problem with linux. It also worked with this other PC yesterday, but
today, after a reboot, it gave me the same problem that the USR.
Minicom says different things when trying to initialize, it can be:
*       ..+++
*       AT S7=45 S0=0 L1 V1 X4 &c1 E1 Q0
which is the good init string, but I still can't type 'at'
*       TQ0V1H0
minicom always gets stuck after this. Then I'm forced to kill it.

Kind of a voodoo trick, isn't it?

1. kppp sometimes won't initialized modem

Sometimes kppp won't initialize the modem. Doing a cold boot solves this
problem.  When it is working the log window displays the initialization
string, then go on to connect. When it doesn't work, kppp says it is
initializing the modem, but the log window remains blank. If I quit kppp
and try again it says the modem is busy. Any ideas of what is going on?
