SSIGNMENTS
If UseDTRin is set to OnDTR, then pin 1 is interpreted only as RTS, and pin 3
is interpreted as DTR, as shown in Table A-3. The behavior of the single
output control signal (pin 28) has not changed. If FlowCtrlFrom is set to
CTS_RTS, the signal is used as CTS to flow-control the attached device. If
not, the signal behaves as DCD according to the configuration of the -TERM
UseDCDout parameter. For further information, refer to the Multiprotocol
Communications Software Reference Guide and your software release notes.
