Mode By default, the Serial port serves as a DCE port in both Packet and TDM
modes. However, the Serial port can serve as a DTE port when the unit is in
Packet mode.
If the Serial port connects to a DTE device (such as a FRAD or a router), the
Mode parameter must be set to “DCE.” If this port connects to a DCE device
(such as a DSU/CSU), this parameter must be set to “DTE” (valid only for
Packet mode, not TDM).
Values: DCE, DTE
Default: DCE
NOTICE: DTE mode requires the use of an optional DTE cable. Refer to
Appendix A,"Specifications," for ordering information.
DSR Data Set Ready can be set to “True,” “False,” or “Internal.” The “Internal”
option sets DSR “On” if the port is enabled and “Off” if the port is disabled.
Values: True, False, Internal
Default: True
DCD The Data Carrier Detect parameter can be set to “True,” “False,” or
“Internal.” If set to “Internal,” DCD is “On” when network carrier is being
received from the remote end, and is “Off” when network carrier is not being
received from the far end.
Values: True, False, Internal
Default: True
CTS The Clear To Send parameter can be set to “True” or “False.” If this
parameter is set to “Internal,” the CTS control lead follows the RTS control
lead from the DTE after a delay of a duration established by the RTS Delay
parameter.
Values: True, False, Internal
Default: True
RTS The Request To Send parameter determines where the unit reads the RTS
signal status from. If set to “Normal,” the unit gets RTS from the Serial pin. If
set to “True,” RTS is always perceived as “On.”
Values: Normal, True
Default: Normal
RTS Delay The RTS Delay parameter determines how long the unit waits before it
changes the level of CTS to match RTS when the CTS parameter is set to
“Internal.”
Values: Normal (~30 ms delay), Long (~100 ms delay)
Default: Normal
