Chapter 4 Terminal Interfacing
BKONDEL determines how character deletion is displayed in the Command or Converse mode. With BKONDEL
ON
, the (
BACKSPACE
)
+
(
SPACE
)
+
(
BACKSPACE
) sequence is produced which updates your computer
screen, erasing the character you want to delete.
On a printing terminal, the (
BACKSPACE ) + ( SPACE ) + ( BACKSPACE ) sequence will result in overtyped text.
Set
BKONDEL OFF
if you have a paper-output display, or if your terminal doesn’t respond to the
BACKSPACE
character, ^H ( CTRL - H ). When BKONDEL is OFF , the DSP displays a backslash for each character you delete.
You can get a display of the corrected input by typing the
REDISPLAY
-line character.
CALibrate Immediate Command
Host: Not Supported
CALIBRATE is an immediate command that starts the AFSK transmit tone calibration routine. The DSP-232
provides a continuous on-screen display of AFSK generator tone frequencies in Hertz. The Calibrate command
simplifies transmitter calibration of AFSK levels.
When Calibration is checked all packet connections will be lost, and the time-of-day clock will not advance until
you quit the calibration routine.
Commands available in the calibration routine are:
K
Toggles the DSP-232’s PTT between on and off.
Q Quits the calibration routine.
<space> Toggles the audio tone between “mark” (low) and “space” (high) tones.
D
Toggles between transmitting a continuous tone or alternating the mark and space tones at a rate set by
the radio baud (Hbaud) rate.
CANline
n Default: $18 (
CTRL-X
)
Host: CL
“
n ” 0 to $7F (0 to 127 decimal) specifies an ASCII character code.
The argument “
n ” is the ASCII code for the character you want to use to cancel the line of text you’re typing. You
can enter the code in either hex or decimal.
Say you type some characters or a sentence that you want to erase and haven’t yet pressed the
( RETURN ) key.
Simply enter (
CTRL-X
). If you plan to assign a different ASCII character, you’d still press the (
CTRL
) key first,
then the ASCII character you’ve chosen for CANLINE . For example, say you want to assign $7E (~) as your
CANLINE
character. Enter:
cmd:
CAN $7E
So, when you want to cancel a line of text while in the Command mode, you’d enter
~
.
When you use the
CANLINE character to cancel an input line in the Command mode, the line ends with the
backslash ( \ ) character and a new prompt ( cmd: ) appears on the next line to accept a new command. When you
cancel a line while in the Converse mode, only a ( \ ) and a new line appears.
!
Remember:
♦
You can cancel only the line you’re currently typing.
♦
Once (
RETURN
) has been pressed, you can’t cancel the line of text you just typed in.
Note : If your SENDPAC character isn’t RETURN , the CANLINE character cancels only the last line of a multi-line packet
