Common telnet clients need this when connecting to
130
130
a port other than 23. Defaults to true.

usectl=[0|1]

If true, modem status lines are properly handled in
134
+
both directions. Specifically, DSR is always asserted,
135
+
CTS and CD are only asserted when a client is
136
+
connected to the TCP port, and flashing DTR causes the
137
+
TCP connection to close. This is useful when the
138
+
serial line is a tty, to close the connection when
139
+
logged out and, conversely, to log out when the
140
+
connection is closed manually. Defaults to true.
