[ltp] thinkpad t20 modem

[James Mckenzie]

Matt:

First, my apologies, I have two machines I run Linux on, an A22p and a 
600E.  The 600E uses the mwave modem driver and requires settings in 
order to operate properly.  However, I built my own lt_modem drivers 
because I am not running a standard linux install and have upgraded the 
kernel several times.  

Let me look at the dmesg from where the lt_modem.o driver file loads. 
 Did you get a rpm file or did you download and then build the drivers? 
 If you built the drivers, make sure that they are in the 
/lib/modules/<kernel #>/ltmodem/ directory.  For example if your kernel 
is 2.4.18-24.8.0 this would appear as 
/lib/modules/2.4.18-14.8.0/ltmodem.  If you upgrade your kernel, you 
will have to either download a new .rpm file or build new drivers.  A 
.rpm file should load the driver files into the correct directory.

I meant to say that I had to force the load of the lt_modem.o driver 
with the following line:

insmod -f lt_modem.o

This module is not GPL, and would not load under RH 7.x and RH 8.0 
without the -f (force) option.  On some systems, you might have to 
specify where the modem is located, by specifying its location.  See the 
modules.conf 'chunk' below on the format for this information.

The following is from my modules.conf:

# lt_drivers: autoloading and insertion parameter usage
alias char-major-62 lt_serial
alias /dev/tts/LT0 lt_serial
alias /dev/modem lt_serial
# The next two lines are syntax examples, only Rarely Needed, to 
automate parameter usage during lt_drivers insertion. See documentation 
for details.
# options lt_modem vendor_id=0x115d device_id=0x0420
# options lt_modem Forced=3,0x130,0x2f8,0
# section for lt_drivers ends

Also, if /dev/modem exists before you install the lt_modem drivers, you 
WILL have to delete it.  Also, if you insert and remove a PC Card modem, 
you will lose the link to the lt_modem driver and have to reestablish it.
