Description

device connected to the system. Specify normal or
inverted, as appropriate. In most cases, normal signaling
is appropriate.
If your system is connected to Ascend equipment, you
may need to set CTS to Ignore.
Specifies that the system should begin the call when it
detects a DSR signal.
Specifies how long the system waits to end the call after
a DCD signal is lost (for example, during a call via
satellite).

site hangs up. When the pulse is too short, the call may
not clear.
If your system is connected to ADTRAN equipment, you
may need to adjust DTR pulse duration.
Specifies whether the call starts when H.320 data is
detected at the V.35 interface while set for direct
