Serial ports 1 through 4 are configurable as modems (DCE) for connection
to terminals, or as terminals (DTE) for connection to modems. The
MVME712M is shipped with the serial ports configured for DTE
operation. Serial port DCE/DTE configuration is accomplished by
positioning jumpers on one of two headers per port. The following table
lists the serial ports with their corresponding jumper headers.

Serial port 4 can be configured via J15
RtxC4 signal lines. Part of the configuration is done with headers J16, J17,
