RTS/CTS Delay The Request To Send/Clear To Send 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
CTS The Clear To Send parameter 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.
Values: Forced True, Forced False, Internal
Default: Forced True
DCD The Data Carrier Detect parameter 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
DSR 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
LL The Local Loopback parameter can be set to “Enable” or “Disable.” Selecting
“Enable” allows the unit to go into Local Loop when the LL pin on the Serial
port goes high. The unit exits the loop when the LL pin goes low. If you
select “Disable,” the unit ignores the LL pin on the Serial port.
Values: Disable, Enable
Default: Disable
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
Current Pin Status Shows the 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 go into alarm on a 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.
