V 54 Selecting “Enable” allows the unit to respond to in-band V.54 loop codes. If
you select “Disable,” the unit ignores these codes.
Values: Disable, Enable
Default: Disable
C T S The Clear To Send can be set to “Forced True,” “Forced False,” or “Internal.”
If this parameter is set to “Internal,” the CTS control lead follows the Request
to Send (RTS) control lead from the DTE after a delay of a duration
established by the RTS/CTS Delay parameter (see RTS/CTS Delay on
page 3-24).
Values: Forced True, Forced False, Internal
Default: Forced True
D S R Data Set Ready can be set to “Forced True,” “Forced False,” or “Internal.”
The “Internal” option sets DSR “On” if the port is enabled and “Off” if the
port is disabled.
Values: Forced True, Forced False, Internal
Default: Forced True
D C D Data Carrier Detect can be set to “Forced True,” “Forced 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: Forced True, Forced False, Internal
Default: Forced True
R T S Request To Send determines the source from which the unit reads the RTS
signal status. If set to “Normal,” the unit gets RTS from the DTE on the
Serial interface. If set to “Forced True,” RTS is always perceived as “On.”
Values: Normal, Forced True
Default: Normal
R T S /C T S D elay Request To Send/Clear To Send 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
C u rren t P in S ta tu s Displays the Current Pin Status of the DTE Serial port pins.
DTR Alarm Control and Status Table
In addition to the configurable fields, the Serial screen displays a table that
lets you set the Data Terminal Ready (DTR) Alarm Control parameters and
view the current DTR Alarm Status.
Choices for DTR Alarm Control are “Enable” and “Disable”; the default
setting is “Disable.” Setting DTR Alarm Control to “Enable” allows the unit
to generate an alarm upon loss of DTR, which occurs when the Serial port
detects that the DTR signal is low. The DTR Status field indicates the current
state of the DTR alarm.
