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 MTS 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.
