Don't do that...  (but that's not the cause of the problem).

The modem stopped answering.  Either it died, or the serial port got
"in a bad state".

Make sure you use the *very latest* Cyclades drivers (there have been 
a number of bug fixes) and that you compile your system kernel with
the proper C compiler (gcc 2.7.2.3, do not use egcs or gcc 2.8!).
