Chapter 4 Terminal Interfacing
Same as 5BIT, except that the unit receives a 6-bit code and adds a constant of $30 (48 decimal) to yield a range of
$30-6F. RXREV and RBAUD must be set correctly. SIGNAL is helpful in determining whether a transmission is 6-
bit and the settings for RBAUD and RXREV, but OK will not automatically select 6BIT.
When the user enters 6BIT, the DSP-232 displays “
OPMODE now BAUDOT
”. This is not strictly true; however, the
‘b’ will glow in the Mode window.
Do not change modes directly between BAUDOT, 5BIT, and 6BIT. Go through some other mode first, such as
Packet. There commands do not function in 6BIT: BITINV, CODE, MARSDISP, TRACE, USOS, WRU, and
XMIT.
ACRDisp
n Default: 0
Host: AA
“
n ” 1 to 255 specifies the screen width, in columns or characters.
0 Disables this function.
The numerical value “
n ” sets the terminal output format for your needs. The DSP sends a ( RETURN ) + [LF is
optional] (
LF
) sequence to your computer at the end of a line in the Command or Converse modes when “ n ”
characters have been printed on the computer screen. Most computers and terminals do this automatically so
ACRDISP
defaults to
0
.
When the DSP is in the MORSE mode, received data will be broken up on word boundaries, if possible. At a
column of 12 less than the
ACRDISP
value, the DSP starts looking for spaces in the received data. The first space
received after this column forces the DSP to generate a ( RETURN ). If ACRDISP is 0 (default), this occurs at
column 60. If there are no spaces at—or after—this column, then a (
RETURN
) occurs at
ACRDISP
.
For example: pretend you’re sitting in front of typewriter and you set it’s right-margin at 60 (characters). This is
like setting
ACRDISP to 60 . As you reach, and pass, character 48—the “12 less than ACRDISP ” value—the DSP
will look for a space between the words you’re typing in. When it sees this space, it’ll force a (
RETURN
) to put
you on the next line. If the DSP doesn’t find any spaces between 48 and 60, or if ACRDISP is set to zero, it’ll force
a ( RETURN ) at 60 .
ADDress n Default: $0000
Host: AE
“
n ” Zero ro 65,535 ($0 to $FFFF) setting and Address in the DSP-232 memory.
The ADDRESS sets an address somewhere in the DSP-232’s memory map. This command is usually used with the
IO, MEMORY and the PK commands. It is used primarily by programmers and is of no use for normal DSP-232
operation.
AFilter ON | OFF Default: OFF
Host: AZ
ON
The ASCII characters in the
MFILTER
list are filtered out and not transmitted.
OFF The ASCII characters in the MFILTER list are filtered from monitored packets only.
Some terminals and computers use special characters to clear the screen or perform other “special” functions.
Placing these characters in the
MFILTER
list, and turning
AFILTER ON
, will keep the DSP from transmitting
them.
!
Exception : when
ECHO
is
ON
and the computer sends a filtered character, the DSP will echo it back to your
terminal or computer.
