Controlling External Devices
Controlling External Devices
If your system is configured to control an external device
,
such as a multiplexer, you can establish a
window
session to it from the control terminal. While in a
window
session, any characters you type at
the control terminal go to the external device for processing. Any characters generated by the external
device appear on the control terminal screen.
The Window to External Device (
window
) command establishes a
window
session. You can use this
command only if the external device connects to the local node. You can, however, enter the
window
command during a virtual terminal session so that you have a
window
session with any external device
in the network.
To start a window session, use the following procedure:
Step 1
First, check the port and the port function with
cnfterm
and
cnftermfunc
.
Step 2
Next, determine whether the external window device is cabled to a node's Control Terminal
(EIA/TIA-232) port or Aux Port (EIA/TIA-232) port.
Step 3
Use the Virtual Terminal (
vt
) command to access the node cabled to the device.
Step 4
Invoke the
window
command. The following format is used for the
window
command:
window [a | c]
Step 5
Enter an
a
if the external device is attached to the node Aux Port or
Enter
c
if the device is attached to the node's Control Terminal port. The default for this parameter is
Aux Port.
Step 6
To establish a
window
session with an external device attached to a node's Control Terminal port, enter
the following syntax:
window c
Step 7
The system responds by redrawing the terminal screen. You can now enter commands and send data to
the external device as if you were locally connected to its Control Terminal port.
While in the
window
session, only commands used to control the external device are recognized.
IGX/BPX commands are not recognized. You might notice a slight transfer delay in transmission, due
to the IGX/BPX bundling of characters before transmitting them. Transfers are delayed until the transfer
buffer is filled, or until the keyboard has been inactive for over 50 milliseconds.
To end a
window
session, enter an escape sequence.
Escape sequences are one to eight characters in length. You configure escape sequences by using the
Configure Terminal Port Function (
cnftermfunc
) command. For example, if you have specified
“signoff” as the escape sequence in the Configure Terminal Port Function, enter the following to end the
window
session:
signoff
The default escape sequence is:
^^ (SHIFT 66)
If this escape sequence does not work and you do not know the configured escape sequence, leave the
keyboard idle for four minutes. After four minutes, the system terminates the window session.
