The tr Command
|
|
tr
|
|
|
|
The tr command selects transparent mode.
|
|
|
|
Format
|
|
|
|
The format for this command is:
|
|
|
|
tr [-2] [port]
|
|
|
|
where:
|
|
|
|
-2 Selects 2-port mode.
|
|
port Selects a specific port
|
|
|
|
Functional Description
|
|
|
|
The tr command selects transparent mode. In transparent mode, the Monitor copies any characters typed on the
|
|
keyboard to the selected port and then copies characters arriving at
|
|
the selected port to the screen. This command can be used for two
|
|
different functions.
|
|
|
|
» To allow the user run the Monitor on the same serial port that
|
|
is used as a login line to your host. Do this by connnecting tty1
|
|
to your host system, and tty0 to your terminal. Typing 'tr' on
|
|
your terminal will connect you with your host.
|
|
|
|
» To allow the user to 'rlogin' to another board via a serial port
|
|
or pseudo tty port. This mode is used on the ATMizer platform
|
|
in order to 'talk' to the SAR board. For example,
|
|
|
|
PMON tr tty2 connect to port tty2
|
|
SAR r display registers on SAR board
|
|
^K return to main board
|
|
PMON r display registers on main board
|
|
|
|
tty2 is the name of the pseudo tty port (located in shared
|
|
memory) that is used to communicate with the SAR board.
|
|
|
|
Note that if you are using 2-port download mode. You will need
|
|
to add the option '-2' to indicate that you need 2-port transparent
|
|
mode. For example,
|
|
|
|
PMON tr -2 tty2
|
|
|
|
In this case the Monitor not only copies
|
|
characters typed on the keyboard to tty2 and characters arriving
|
|
on tty2 to the screen. It also copies characters arriving on tty1
|
|
to tty3, and characters arriving on tty3 to tty1.
|
|
|
|
The trabort Variable
|
|
|
|
The environment variable trabort selects the character that terminates
|
|
the transparent mode and returns the Monitor
|
|
to the default command mode.
|
|
|
|
The hostport Variable
|
|
|
|
The environment variable hostport determines the default port for the
|
|
tr command.
|
|
|
