The model > number is a 201B. Many thanks. Bill: The UDS 201B is a 2400bps half-duplex synchronous modem, suitable for leased-line or dial-up service with other 201-style equipment. (Some models will support full-duplex synchnonous service using 4-wire leased lines. All are half-duplex on dial-up lines.) They're usually used between IBM 3270-series cluster controllers and remote host system channel adaptors. Probably not very useful in the world of asynchronous full-duplex service we tend to use with Unix. Dave Levenson Voice: (201) 647 0900 Westmark, Inc.
