The RS-232C port on the MPB does not support hardware flow control.
Referring to the pin-out chart above and the wiring diagram below,
wire the RS-232 port to an appropriate DTE (Data Terminal Equipment),

5.2.8 DSIU (Digital and Single Line Interface Unit) Wiring
The DSIU is included on the MPB and provides six (6) Digital Terminal (DKT-1 to 6) ports and six (6)
Single Line (SLT 1 to 6) ports. The DSIU SLT ports support FSK (ITU-T V.23 or Bell 202) or DTMF
(ITU-T Q.23) Caller ID to the SLT. The SLT ports provide the -48 VDC source, current limited to 20
mA, to operate the SLT, and support Message Wait Indication, DTMF or Pulse Dial, Polarity reversal,
sinusoidal ring generator, and GR-909 Line Testing. The SLT and DKT ports of the DSIU are
terminated in RJ45 connectors located in the front panel of the board. Note the DSIU is NOT field
replaceable.
