COMA (RS-232) available either on the front panel or on the CompactPCI rear I/O interface
COMB (RS-232/RS-422) on the CompactPCI rear I/O interface
COMA and COMB are fully compatible with the 16550 controller. The rear I/O COMA port includes a complete set of
handshaking and modem control signals. The COMB port includes RXD, TXD, CTS, and RTS signals.
The COMA and COMB ports provide maskable interrupt generation. The data transfer on the COM ports is up to
115.2 kbit/s.
The serial port COMA is implemented as an 8-pin RJ-45 connector, J8. The following figure and table provide
