Chuck,
Well I tried emailing you direct, and it bounced sooo... anyways, the CS21
is, according to the Spring 1988 Emulex Products Catalog, a multiplexer
which comes in three flavors. Yours is the /H, which would make it a DH11
equivalent. It is indeed a 16 line, asynchronous mux, 19.2Kbps max speed,
full duplex transmission, partial modem control, 50,000cps throughput, and
receive fifo of 64-256Kw per 16 lines. Hope that helps some...
Will J
