The Printer M is a high-performance, direct memory access (DMA) single-line - programmable communications controller that provides interconnection between Q bus systems with Printer RS 232 C/Printer V.28, EIA RS 422/CCITT V.11, and - - - - EIA RS 423/CCITT V.10 interfaces. It is capable of communications speeds up to - 64,000 bits Printer per second. Used an the MicroVAX II system, it utilizes the Micro/ T-11 processor to Printer perfrom user-defined communications functions, freeing the host to do more application computations. The KMV1A-M can be programmed in synchronous or asynchronous modes. It also provides full modem support for Digital's Printer family of modems, and the Bell 200 series or equivalent. Printer M sup- - ports a software tools package, X.2Printer5 link level, and Printer framing software.
