* UNET (3Com) TCP-IP server for uucico.
* uucico's UNET channel causes this server to be run at the remote end.
* An argument, if present, is the local port number.
* This server does a tcpopen(III) to establish the connection,
* renames file descriptors 0,1, and 2 to be the UNET connection,
* and then exec(II)s uucico.
