All PLC-5/VME processors have at least one configurable I/O channel and
one serial port (channel 0).
Channel: Is configured for:
0 supporting RS-232C
The PLC-5/VME processor channel 0 protocol defaults to the system mode of
operation (DF1 point-to-point), which allows programming from a PC terminal.
The default communication rate is 2400.
1A DH+ mode (by default)
1B scanner mode (by default)
2 (if applicable) DH+ and remote I/O (RIO) communication or extended-local I/O
