Host: TM
“n” 0 to $7F (0 to 127 decimal) specifies an ASCII character code.
TIME specifies which control character sends the time-of-day in the text you type into the transmit buffer or into a
text file stored on disk.
At transmit time, the DSP reads the time-of-day from the DSP’s internal clock then sends the time to the radio in the
data transmission code in use at that time. If
DAYTIME hasn’t been set, a ( CTRL-T ) will cause the DSP to send an
asterisk (*). With DAYSTAMP ON , the date is transmitted with the time.
Note :
TIME
can’t be embedded in
CTEXT
,
BTEXT
,
MTEXT
or
AAB
.
Trans
Immediate Command
Host: Not Supported
TRANS
switches the DSP from the Command mode to Transparent mode; the current state of the radio link isn’t
affected. Transparent mode is primarily useful for computer communications since Transparent mode “human
interface” features such as input editing, echoing of input characters, and type-in flow control are disabled.
♦
Use Transparent mode for transferring binary or other non-text files.
♦
To exit the Transparent mode, type the COMMAND character, ( CTRL-C ), three times within the time
period set by
CMDTIME
(default:1 second).
TRFlow ON | OFF Default: OFF
Host: TW
ON
Software flow control for the computer or terminal receiving data is enabled in Transparent mode.
OFF Software flow control for the computer or terminal receiving data is disabled in Transparent mode.
With
TRFLOW ON , the type of flow control used by the computer receiving data in the Transparent mode is
determined by how
START
and
STOP
are set.
With
TRFLOW OFF , only “hardware” flow control (RTS, DTR) is available to the computer when receiving data
from the DSP (while in Transparent mode).
With
TRFLOW ON
, and
START
and
STOP
are set to values other than zero, software flow control is enabled for
your computer. The DSP responds to the START and STOP characters while remaining transparent to all other
characters from the terminal.
TWRcv n Default: 50
Host: Tr
n
0-100 adjusts how the DSP-232 manipulates amplitude of received signals on 1200 bps Packet.
Twist receive (TWRcv) allows you to compensate for poor signal reception by adjusting the amplitude of the high
tones. Entering values less than 50 allow you to lower the amplitude of the received signal’s high tone. Entering
values greater than 50 allow you to increase the amplitude of received signal’s high tone.
TWXmt n Default: 50
