Disable = an outgoing connection is never attempted.
Any Character = a connection is attempted when any character is read on
the serial line.
Start Character = a connection is attempted when the start character for the
specific tunnel is read on the serial line.
Modem Control Asserted = a connection is attempted as long as the
Modem Control pin (DSR) is asserted, until a connection is made.
Modem Emulation = a connection is attempted when triggered by modem
emulation AT commands.

Once you have configured a number, click the Random link in the Current

concern, it is highly
recommended that SSH

both the SSH Server Host
Keys and SSH Server

Virtual IP identified by the VIP Name. When VIP is enabled, the Host 2 field
