Chapter 9 AMTOR Operation
TAB. At the moment, this protocol is used only on links between mailboxes forwarding messages. It could be used
with the AEA AMTOR-to-Packet Gateway if all users had CODE 8. (CODE 8 isn’t invisible to other users.)
CWid
n
Default: $06 (
CTRL-F
)
Mode: Baudot/ASCII RTTY/AMTOR/PACTOR/FAX
Host: CW
The
CWID
command lets you change the “send CWID” control character typed at the end of your Baudot and
ASCII RTTY dialogue.
When the DSP reads this character embedded in the text or keyboard input, it switches modes and sends your
callsign in Morse code, at the keying speed set by
MSPEED
. As soon as your callsign has been sent in Morse, the
DSP turns off your transmitter and returns to receive.
DCdconn
ON
|
OFF
Default: OFF
Mode: packet, AMTOR, PACTOR, KISS and RAWHDLC
Host: DC
OFF
RS-232 cable Pin 8 is permanently set high (default).
ON
RS-232 cable Pin 8 follows the state of the CON (or DCD) LED.
DCDCONN
defines how the DCD (Data Carrier Detect) signal affects pin 8 in the RS-232 interface to your
computer or terminal. Some programs such as PBBS software require that
DCDCONN
be
ON
.
DCDCONN
also works in the
RAWHDLC
and
KISS
modes. In
RAWHDLC
and
KISS
, no packet connections are
known to the DSP. With
DCDCONN
ON
, the state of the radio DCD is sent to the RS-232 DCD pin (pin-8). This
may be necessary to some Host applications that need to know when the radio channel is busy.
EAS
ON
|
OFF
Default: OFF
Mode: Baudot, ASCII, AMTOR, PACTORand MORSE
Host: EA
OFF
Echos characters when sent to the DSP by the computer.
ON
Echos characters actually sent on-the-air by the DSP.
The Echo-As-Sent (
EAS
) command functions in all modes
except
packet.
EAS
lets you to choose the way data is
displayed on your monitor screen or printer. To display your text on your computer screen exactly as you’re typing
it in or while sending it from a disk file, leave
EAS
OFF
. To see the actual data being sent from your DSP-232 to
your radio and transmitted on the air, set
EAS
ON
.
With
EAS
ON
in Morse and Baudot RTTY, you’ll see only uppercase characters on your screen and the data
actually transmitted to the other station.
With
EAS
ON
in AMTOR mode A and PACTOR (ARQ), you’ll see characters echoed on your screen only
after
the distant station has validated
ack
ed your block of three characters. For packet, the
MXMIT
command should be
used.
Nulls ($00) are not echoed, including the nulls produced by
DIDDLE
ON
in ASCII.
ERrchar
n
Default: $5F (_)
Mode: AMTOR, PACTOR, Morse, NAVTEX and TDM
Host: ER
“
n
”
A hexadecimal value from $00-$7F used to denote the error character used by the DSP for Morse, ARQ,
FEC, PACTOR, NAVTEX, and TDM.
