Re: Connecting serial based modem to Ubuntu via a PCI express multiport Serial board

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There was an earlier similar case of a Linux compatible serial
multi-board.   Though there was a Linux driver provided, some
modification was necessary to acquire functionality in the specific
host environment.   Afterwards the procedures Antonio described worked
for a serial modem attached.

Unfortunately, I'm travling now with only occassional Internet access,
through Tuesday.   If our Archives are searched for "multi-board" or
similar, you may be able to retrieve the record.
