This should work. I changed mine to set the modem ports to 38400, so that
the serial interrupts were not as frequent with several V.34 modems.   Make
sure to turn on RTS/CTS pacing on your modems!

Here comes a new version of rc.serial. It is set to cooperate with
Cyclades. I didn't try to start it with Specialix.
