Modem dropping connection

Jon Jenkins_1 — Mon, 10 Dec 2001 16:45:31 GMT

We have a external ERP company that dials in to bug fix on HPUX 11.0 server. They have reported that at certain times the connection gets dropped. They haven't been specific as to whether this is after a certain amount of time or...? Is there a log file I can investigate this in (or switch on) and what sort of things should I be looking for? What things do I need to check for the configuration of the modem?

Any help/links etc. most appreciated.

Hi,

One thing I can suggest is to reduce the speed to 9600bps and test for a while.
Also these modem configurations have some thing called S registers. You can check in modem manual to set it to hold the line. If I'm not wrong then it should be s10 register.

Goodluck,

You can check the modem settings by doing a 'cu -l /dev/tty?' where ?=serial port. Be sure to have the manual for your modem handy, usually the commands L5 through L9 will show various settings, as will Sr? where ?=number of the register to display.

Thanks guys, definitely pointed me in the right direction, it was S30 that holds the default idle time. Thanks.
