ComConnected:
Next Edit Clear Prev
Carrier Communication Port Connect Indication String. Specifies the communication
port’s connect indication string. When you make a connection or the DSU/CSU
automatically makes a connection (dial-out alarms or traps) through the communication
port, this string determines that the connection has been established. The connect
indication string is an ASCII text string and may be up to 20 characters in length. If the
connect indication string is not received within 1 minute, it will time-out the connection. If
the connect indication string is NULL, the communication port’s receive data stream is not
searched and a transition in the Carrier Detect (CD) lead is used to determine that a
connection has been established.
Edit
– Allows you to edit and/or display the case-sensitive connect indication string using
the generic text string entry screen.
Clear
– Allows you to clear the connect indication string. The connect indication string is
set to a null string.

ComEscapeSeq:
Next Edit Clear Prev
Carrier Communication Port Escape Sequence. Specifies the communication port’s
escape sequence. Once the external device connection has been established, either you
or the DSU/CSU can command the external device to disconnect. Before doing so, you
may need to send the escape sequence out to switch the external device into command
mode. The escape sequence is an ASCII text string and may be up to 20 characters in
length. If the escape sequence is NULL, no escape sequence is sent out.
Edit
– Allows you to edit and/or display the escape sequence using the generic text string
entry screen.
Clear
– Allows you to clear the escape sequence. The escape sequence is set to a null
string.
