Dear All,
I give up! According to everything I've read the Netmos 9845
chip should be supported by the latest kernel and work out of
the box, but it doesn't. (It DOES work in Win XP) Using setserial
to correct the errors doesn't seem to help - there is no signal
emerging from the ports.
I've tried the set/get_multiport options but get the response
Cannot get multiport config: invalid argument
I've tried the fourport option - also doesn't work.
What's left - get a new card??
