Description of port setting options in the classic 2.x or 3.x Com Port Redirector

I'm not sure what options I need to select when configuring a COM port created with the 2.x or 3.x Redirector. Is there a description available?


Note: This information is for the obsolete 2.x and 3.x Redirector. For information on configuring the current 4.x CPR (Com Port Redirector) see the Quick Start Guide on this page, or open the CPR help system from the CPR Manager application:

Setting

Description

Timeout Reconnect

If checked, Com Port Redirector re-establishes the connection if the connection times out (see the TCP Keepalive information in your device server user's guide). When auto-reconnecting, Com Port Redirector tries to reconnect until the connection succeeds or you click the Cancel button in the pop-up connection dialog box. If the port was closed by the communications application or by clicking Disconnect, Com Port Redirector does not try to auto-reconnect.

Server Reconnect

If checked, Com Port Redirector re-establishes the connection if the server closes it. When auto-reconnecting, Com Port Redirector tries to reconnect until the connection succeeds or you click the Cancel button in the pop-up connection dialog box. If the port was closed by the communications application or by clicking Disconnect, Com Port Redirector does not try to auto-reconnect.

Inband Listen

If checked, Com Port Redirector uses the inband redirector protocol on inbound connections from a Lantronix server. This protocol allows settings like modem signals, baud rate and parity to be exchanged between Com Port Redirector and the server.

To use this setting with MSS and ETS products, the server must run firmware V3.6/3 or higher and the word OR must be specified at the end of the server's connection (Define Port) string. See your product reference manual for more information.

To use this setting with SCSxx00 products, the server must run firmware V2.0/1 or higher and the word OR must be specified at the end of the server's connection (Define Port) string. See your product reference manual for more information.

Connection Timeout

Specifies the maximum number of seconds that the Com Port Redirector waits for a connection to be made before giving up on this attempt. If Timeout Reconnect is enabled, each connection attempt lasts this long. If Timeout Reconnect is disabled, the connection attempt fails after this interval and no more attempts are made.

Force v2 Protocol

If checked, Com Port Redirector always uses the version 2 protocol. This protocol has a quicker connect time than version 3, but lacks the version 3 feature set. Version 3 lets the communication application set the Data Terminal Ready (DTR) and Request To Send (RTS) states, byte size, stop bits, parity, and the read the state of Clear To Send (CTS), Data Set Ready (DSR), and Carrier Detect (CD). CoBox, UDS, XPort, and XPress products do not support version 2 or 3 Com Port Redirector protocols. Therefore, use Raw Mode with CoBox, UDS, XPort, and XPress products.

No Net Close

If checked, prevents the network connection from being dropped when the communications application is closed. To drop the connection, click the Disconnect button in the Com Port Redirector Configuration window. This allows applications to close and reopen ports, without waiting for the network connection to be re-established and negotiated.

Raw Mode

If checked, forms a raw TCP connection to the server's serial port, accelerating the connection between the communications application and the server, without sending configuration or status information from the PC to the server. Raw Mode is designed for CoBox, UDS, XPort, and XPress products. When using Raw Mode, configure Com Port Redirector and your Lantronix server to use the same port number.
