Comm Port Redirector
5.3.5 Port Settings
If auto reconnect is enabled, the redirector will try to reestablish the network connection if the
connection goes down.(Cant find this option) If Timeout Reconnect is enabled, the
connection will be reestablished if the connection times out (see TCP Keepalive). If Server
Reconnect is enabled, the connection will be reestablished if the server purposely closes the
connection.
When auto reconnecting, the redirector will keep trying to reconnect until the connections
succeeds or the user hits Cancel in the popup connection dialog.
If the port was closed by the comm app or by clicking Disconnect, then the redirector does
not try to auto reconnect.
The Connection Timeout is the number of seconds to attempt a connection before failing. If
auto reconnect is enabled then each connection attempt will last this long. If auto reconnect
is disabled then the connection attempt will fail out after this interval.
5.3.6 Listen Mode
The redirector can be set up to listen for an incoming connection over TCP/IP. In this mode,
when the comm app opens the COM port the redirector tells the comm app that the port is
open, but goes into a listening state. When the server initiates a connection into the PC, data
transfer between the PC and the server proceeds normally. The redirector can be configured
in one of two listen modes:
1. Listen once
In this mode the redirector will accept an incoming connection and if the remote side closes
the connection, the redirector will notify the comm app that the port is closed. The comm app
has to re-open the port in order to go back into listen mode.
To configure this mode set the IP host name field in the IP Service Setup screen to "listen"
(without the quotes) and set the port number field to the port that the PC will be listening on.
For instance, if you wanted the PC to listen on port 3200, set the host name to "listen" and the
port to 3200.
2. Listen auto
In this mode the redirector will accept an incoming connection and if the remote side closes
the connection, the redirector will automatically go back into listen mode without notifying
the comm app that anything has happened.
To configure this mode set the IP host name field in the IP Service Setup screen to
"listen_auto" (without the quotes) and set the port number field to the port that the PC will be
listening on. For instance, if you wanted the PC to listen on port 3200, set the host name to
"listen_auto" and the port to 3200.
