Wan Rs232 128-Port Adapter (F/C 2944) - IBM RS/6000 SP Handbook

This adapter provides a single DB-78 output that connects directly to the 8-port
DB-25 connector box. All eight ports are software programmable to support
either protocol at baud rates up to 230 K. The full set of modem control lines for
asynchronous communication are provided for each port. Devices such as
terminals, modems, processors, printers, and controllers may be attached.
