PCMCIA: Serial Connection Terminates

Support knowledgebase (ratschker_serial_abbruch)
Applies to

SuSE Linux: Versions 6.2 to 7.3

Symptom:

You run a PCMCIA card with a modem on your laptop. The modem has been detected e.g. by wvdial and the serial connection to your ISP can be set up without problems. The data transfer works smoothly, too.
However, the connection terminates after a while without any apparent reason. The same happens to the PPP daemon.

Cause:

The cause of this phenomenon has not been found yet.
We would like to thank the customers who have helped us to solve this problem.

Solution:

Try to solve the problem by executing the command

setserial /dev/modem spd_vhi
or
setserial /dev/modem spd_hi


If the outcome is successful, you can make that setserial is automatically executed with this option by entering this parameter in the file /etc/pcmcia/serial.opts.

# Options for 'setserial'
  SERIAL_OPTS="spd_vhi"
