Micheal:

Look at the output from dmesg for the lines associated with the lt_modem 
driver.  They should look like the following:

Loading Lucent Modem Controller driver version 8.26
Detected Parameters Irq=11 BaseAddress=0x1800 ComAddress=0x1c00
Lucent Modem Interface driver version 8.26 (2002-11-04) with SHARE_IRQ 
enabled
ttyLT00 at 0x1800 (irq = 11) is a Lucent Modem

You should be able to 'cat' /dev/ttyLT0.  

Also did you check for the link between /dev/modem and /dev/ttyLT0?

If it exists you should be able to start up kppp and run the terminal 
program and check the output of the atz and ati series of commands.
