Ok, so it doesn't use the ZyXEL/IS-101 command set. Does AT#CLS=8
work? In that case you could try the Rockwell/USR driver.

Bad luck, but one question I'm really wondering about is, if you
tried the Sierra driver in vgetty? If your modem is not detected, you
just have to add the one/some lines to the auto detection routine.
Please send me the output of the ATI commands (ATI, ATI1, ATI2, ...)
and I can tell you exactly what to add where.

Logfiles? What happens exactly?
