.th MX IV 8/5/79 .sh NAME mx - indirect driver for multiplexed tty ports .sh SYNOPSIS .it tty[??] are ports multiplexed onto real tty lines used for communication links to other Unix hosts. .sh DESCRIPTION When one of these ports is opened for reading or writing, it behaves exactly as if it were a normal tty line. Speed changes will do the right thing, though of course the real line speed is fixed. .s1 The driver uses a minimal protocol to block port messages onto the real line, so 1 byte writes are the least efficient. If you can avoid it, don't use remote echo (i.e. "stty -echo"). .sh FILES /dev/tty[??] .sh "SEE ALSO" tty (IV), stty (I) .sh AUTHOR Piers Lauder (Sydney University)
