Description of Commands
PORT
The PORT command can be used to connect to either an installed Ethernet
card or a remote relay.
PORT p
The PORT p command connects a relay serial or ethernet port to another
device through a virtual terminal session.
In the SEL-421, serial port virtual terminal capability is available in
M
IRRORED BITS communications. You must have previously configured the
serial port for M
IRRORED BITS communications operation, set port setting
MBNUM less than 8, and have at least one virtual terminal session available
(set MBNUMVT to 0 or greater). Choosing MBNUMVT to 0 uses virtual
terminal within the synchronization channel only. See SEL M
IRRORED BITS
Communications on page R.5.15 for information on the M
IRRORED BITS
communications protocol.
If an Ethernet card is installed, you can use the PORT command to initiate a
virtual terminal session with the communications card by specifying port
number p as 5.
When the relay establishes a connection, the relay responds,
Transparent
session to Port p established
. To quit the transparent connection, type
the control string that you specify in port setting TERSTRN; the default is
<Ctrl+E>. Only one transparent port connection to each M
IRRORED BITS
communications port is possible at one time. If you issue a PORT p command
when the selected session is already active, the relay responds,
Transparent
session already in use
.
If you issue the PORT p command to ports 1, 2, 3, or F and you have not
properly configured the M
IRRORED BITS communications port or the
MBNUMVT is not set to 1 or larger, then the relay responds,
Invalid
destination port
.
PORT KILL n
It is possible to forcefully disconnect a transparent session from another port
(a port not involved in the present transparent connection) by using the PORT
KILL n command (shown in Table 9.92).

PORT KILL n
a
a
Parameter n is 1, 2, 3, F, or 5 to indicate Communications PORT 1 through PORT 3, PORT F, or
PORT 5; n is not the present port.
Terminate the virtual terminal connection with
a remote device through port n by using a port
not involved in the connection.
