editbrk
When not in the Interactive mode, a user can enter
editbrk
to edit or view their preset break
sequence. The break
sequence is presented in its ASCII form (x1bB). The user key stroke
default is <
ESC>B
. Press Enter to keep the existing setting.
Warning!: Because the sysadmin is responsible for configuration changes, it is
recommended that only the sysadmin be allowed to change the
break
sequence.
9.3.3.2 Escape Sequence
A user-defined sequence of keys is used to leave the Interactive mode. The default
sequence is <
ESC>A
!
Note: Do NOT use combinations of the
<CTRL>
key and other keys for the escape
sequence as these combinations are usually reserved for sending and receiving special
characters through a terminal.
Edit Escape Sequence: It is recommended that only the sysadmin edit the
escape
command
sequence. When logged in, enter
editesc
to edit or view the preset
escape
sequence. The
escape
sequence is presented in its ASCII form (x1bA). The user key stroke default is
<
ESC>A
. Press Enter to keep the existing setting.
Warning!: Because the sysadmin is responsible for configuration changes, it is
recommended that only the sysadmin be allowed to change the
escape
sequence.
9.4 Monitor Mode
Monitor Mode allows a user to view the traffic on a port, but not to interact with it. Once in
Monitor Mode, pressing any key will close the connection. Multiple users may monitor the same
port at one time, unlike Interactive mode, which is limited to one user. A port may be monitored
while an interactive session is in progress. The
monitor
command uses the same syntax as
the
connect
command.
9.5 Browse the Buffers
Any of the Linux text browsing commands (
less, more, ftp, tftp, scp,
etc.) may be
used to view the Port buffers. These buffers are named:
/lsi/ports/buf_<name>
or
/proc/port_buffers/<number>
9.6 Clear the Port Buffers
Use the following commands to erase the data in a Port buffer:
stty --clear -F/proc/port_buffers/<n>
or
stty --clear -F/lsi/ports/buf_<name>
