Four Port RS-232-C Interface Board (#6267, P/N 09F1955).Provides four

EIA RS-232-C/CCITT V.24 serial I/O ports. The InterfaceBoard attaches

to the Coprocessor adapter and includes a 78-pin connector.

Asynchronous, bit synchronous, and character synchronousprotocol

hardware support on first two ports. Asynchronous hardwaresupport on

remaining ports. Can support 19.2K bps full duplex ASYNCprotocols and

38.4K bps full duplex HDLC/SDLC protocols on either of thefirst two

ports. Only one Four Port Board may be attached to aCoprocessor
