Hope someone can help!
I run Mandy 9.1 on a Sony Vaio laptop and have a Xircom 56k pmcia modem attached to ttsy2 (I think). Occassionaly the modem stops repsonding even though the pppd process is still running, in the past I have sent the laptop to sleep, which in turn switches off/on the modem. Occassionally this causes the whole machine to lockup

.
Is there a way to stop and re-start the modem from the command line as the sleep method is too drastic to fix the modem?
Cheers.
