Long Space Disconnect Y
One method of disconnecting two modems is called long space discon-
nect. When any disconnect condition is detected by the local modem, it
will send 4 seconds of data space condition to the remote modem before
disconnecting. This signals the remote modem to disconnect. The local
modem will disconnect if it receives 1.6 or more seconds of data space
condition from a remote modem. If break sequences of 1.6 or more
seconds are to be sent, enter the Y command to disable this feature and
prevent unintentional disconnects.
Note
This option must be disabled if SDLC NRZI data is used.
