Hi,
I would like to write an application on minix, to send and receive
voice over tcp, received from a voice modem. So the questions are:
-Is there any sample c code to interface with the comm port?
-I choose minix because I think it has lower overhead than others OS,
and I will need all the processor time I can get, is minix a good
choice?
thanks, any pointer appreciated

PS: I know I posted this question before, but thought that maybe I
didnt explain myself or that, because it was Saturday night, everyone
was out having fun, and not writing some code...or reading newsgroups.

You might look at
serial-ip (8)
slip (8)
kermit (9)
and the associated code.

The only good alternative choice here isn't free.
It's LynxOS.

As minix currently doesn't save FPU state while context switching,
ack (and gcc) generate software floating point code. It's not
necessarily _too_ slow..
