VirtualPort for Windows
continued
Connection
• “Connect at system startup”—When enabled, VirtualPort will try to connect to the
Console Server when the VirtualPort service starts (as opposed to waiting for the
application to open).
• “Time between connection retries” specifies the number of seconds between
TCP connection retries after a client-initiated connection failure. Valid values are
1-255. (The default is 1000 milliseconds and VirtualPort will continue attempting to
reconnect forever to the Console Server at this interval.)
• The “Send keep-alive packets” option tests if the TCP connection is still up when
no data has been sent for a while by sending keep-alive messages. Select this option
and specify period of time (in milliseconds) after which VirtualPort sends a command
to remote Console Server end in order to verify connection’s integrity and keep the
connection alive.
• The “Keep-Alive Interval” specifies the number of seconds to wait on an idle
connection before sending a keep-alive message. The default is 1000 milliseconds.
The “Keep-Alive Timeout” specifies how long VirtualPort should wait for a keep-alive
response before timing out the connection.
Note: In the event of a “Keep-Alive Timeout,” ensure the remote serial device is
connected to the nominated port on your remote Console Server and the serial port
has been configured, i.e., set the RS232 Common Settings such as baud rate, select
Console Server mode for the port and specify the appropriate protocol to be used (RAW
TCP, RFC2217 or VirtualPort Secure mode for encrypted communication). Also ensure
you can access the Console Server.
• “Disable Nagle Algorithm”—The Nagle Algorithm is enabled by default and it
reduces the number of small packets sent by VirtualPort across the network.
Configuring a COM Port
• To configure a COM port, simply click on the desired COMx label.
• You can then configure the COM port in the Connection and Advanced windows:
