This is a PC/104 adapter module that supports removable CompactFlash cards while offering hard disk software compatibility. Serial Communications - A dual 16C550-compatible port provides two independent, double-buffered, full- duplex, asynchronous serial channels. Each channel has a 16-byte FIFO for the transmit and receive chan- nels. The ports are mapped at COM1 and COM2 respectively which offers software compatibility with PC-type driver programs. Independent control of transmit, receive, line status and data set interrupts are on both channels. Each channel is setup to provide internal diagnostics such as loopback and echo mode on the data stream. The unit contains two independent on-chip software program- PCM-586 BLOCK DIAGRAM mable baud rate generators selectable from 50 through 115.2 K bits per second.
