Hi

I have Boca16 serial port connected to 486 66MHz machine running
FreeBSD 2.0.5.

Currently I have connected 5 Microcom modems (28.8) to Boca16. Each serial
port is configured for 115200 bps.

I am seeing random hangup on this modems. It is at the point were lot of
users are complaining. This is happing even when there is only one modem is
active. 

Has anybody seen this?

By any chance this is because of the DTR drop from the Boca16 to modem?
(The default is 0.05 second, should I change this to higher value -0.10-?
Will this make difference? Or I am on the wrong track?)

Any suggestions?

I had practical peripheral before this and I did not see this problem.

Some time I get message like this:

"/kernel: pid 19306 : ppp: uid 0: exited on signal 10"

Please help.

Thanks,
Tushar
