Need help with Unisys 6000 hangup time

[Winfried Koenig]

I use some SCP (Serial Communications Processor) port for my modem.
Stty parameters are:

speed 19200 hupcl -clocal ... v24 -v24sw v24fdx ctscd

When carrier is lost, the modem turns off DSR and DCD for up to 12.5 sec.
This time is not enough to generate the SIGHUP signal. The SCP needs
more than 16 sec to generate SIGHUP.

What is the reason for this long delay?

How can I reduce this delay to less then 10 sec?

Please respond via email.

Thanks in advance

Winfried
