Schweitzer Engineering SEL-2032 - Figure 8.26 PORT Command

Serial Port Communications and Commands
Command Set
PORT n
The PORT command (Access Level 1) connects the master port issuing the
command to the designated port, permitting transparent communication
between the two ports. To terminate transparent communications and return to
SEL-2032 command operation, use the disconnect sequence set for your port.
You cannot connect to a port that is already communicating transparently.
The example in Figure 8.26 illustrates using the PORT command to enter and
exit transparent communications:
*>>PORT 9 <Enter>

Figure 8.26 PORT Command
This example uses the default termination character <Ctrl+D> to exit
transparent communications. You can set the termination string on the master
port using the TERSTRING setting within the SET P command.
When connecting to a printer port, you may add an E parameter to enable
echoing from the SEL-2032 (e.g., PORT 5 E). Using this parameter, you can
see what you are sending to the printer, but you will not see any messages sent
to you by the printer.
To select the Direct Transparent mode, add the D parameter to the PORT
command (PORT n D, where n selects the port number). The Direct
Transparent mode passes characters through rapidly, without significant
buffering delays and disables RTS/CTS handshaking regardless of the
RTS_CTS setting for the port. Direct Transparent mode also suspends
processing of all logic settings, automatic messages, and math/movement
settings.
If you have a card that supports virtual terminal features installed in Ports 17
or 18, use the PORT command to establish communications with other
devices on the network. Refer to your protocol card instruction manual for
more information.
See Transparent Communications on page 7.8 for a more complete discussion
of transparent communications.
If the NOCONN bit is set, a transparent connection will not be established and
an error message will be sent (see Restricting Port Access with NOCONN on
page 7.26).
QUIT
The QUIT command (Access Level 0) causes the SEL-2032 to return control
to Access Level 0 from Level 1 or Level 2. The command displays the
SEL-2032 ID, date, and time of QUIT command execution.
Use this command when you finish communicating with the SEL-2032 to
prevent unauthorized access. Control returns to Access Level 0 automatically
after a settable interval with no activity (see the TIMEOUT setting in
Table 7.1). If the port you are communicating with is using LMD Distributed
