We are using Telebit modems (using every baud rate) for uucp (outgoing /incoming) through terminal servers. We have also used SLIP. We've used terminal servers to connecting printers (line and/or laserwriters), modems, and machines not using TCP/IP. Before PRIME finish their telnet/ftp implementation, we use Bridges boxes. Data General version of telnet/ftp was too flakey (bounce at least every other day) for us, so we hooked the serial ports to Bridge boxes. Until we get networked TCP/IP printers (Imagen postscript) or write decnet print-command (for DEC LPS40) for non-DEC machines, we just run the printers off a terminal server. Any unix or VMS can print to these printers without using line drivers or nearby minicomputer because distance limitation. These printers run at 9600 baud or better. We like Cisco terminal servers, but Bridge and Encore have the ability to do some and/or all these functions. Ron just answer the question. He didn't go into details. -- Kevin Hobson - Telecommunications Analyst IV ARPANET: hobson@rutgers.edu Rutgers, The State University UUCP: {backbone}!rutgers!hobson P.O.
