Configuration – Network > Serial > TRANSIP Serial Ports
TransIP is a way of using virtual serial ports for serial connections over an IP socket, in
effect multiplying the number of concurrent serial connections to a router. TransIP can be
configured to actively connect on a TCP socket (i.e. make outgoing connections).
Configuration – Network > Serial > TRANSIP Serial Ports > TRANSIP n
The message at the top of this page states which serial interface is being used for the
TransIP connection.
Listen on port n
This parameter is the TCP port number that the router should listen on.
Connect to IP Address or Hostname a.b.c.d Port n
The IP address or hostname text entry box should contain a valid IP address or the
hostname which the router should use to make the outgoing TransIP connection.
If this parameter is set (i.e. non-zero), the number defined the TCP port number to use
when making TCP socket connections. When zero, TransIP is listening only on the port
defined above.
Send TCP Keep-Alives every s seconds
The value in this text entry box is the amount of time (in seconds) a connection will stay
open without any traffic being passed.
Enable Stay Connected mode
When checked, this checkbox causes the router to refrain from clearing the TCP socket at
the end of a transaction, data call or data session (depending on what the TansIP serial port
was bound to and what protocol it was using). Leaving this checkbox unchecked allows the
router to clear the socket. For example, if the TransIP port is bound to a TPAD and the box
is unchecked, the TransIP TCP socket will be cleared at the end of the TPAD transaction.
Disable command echo
When this checkbox is checked command echo for the TransIP port is disabled. When
unchecked all commands issued will be echoed back to the TransIP TCP socket.
Escape char c
The parameter in this text entry box is the ASCII character used as the escape character
which is by default “+”. Entering this escape character three times followed by a pause of at
least the “Escape delay” parameter below and then an “AT” command will cause the router
to switch back to command mode from online mode. This is equivalent to the “S2” register
setting.
Escape delay s milliseconds
The parameter in this text entry box defines the delay required between entering the escape
sequence (default “+++”) and the “AT” command in order for the router to drop back into
command mode. This is equivalent to the “S12” register setting.
