11.7 Pactor Operating Tips
The following 'Special Function characters" and immediate commands are included for Pac-
tor operating convenience.
Immediate Commands from the Command Mode:
"PT" Selects the Pactor mode
"PACTO" Selects the Pactor mode as above
"PTConn <CALL>" Starts a linked connect and forces Converse
"PTSend" Starts an unproto transmission and forces Converse
"R" Stops sending immediately, forces Pactor Standby
"PTList" Allows reception of both unproto and linked transmissions
"PTHUFF <ON|OFF>" Off = prevents Huffman compression; On = allows automatic
use of compression
"PT200 <ON|OFF>" Off = prevents 200 baud operation; On = allows automatic
speed selection
"PTOver<$HH>" Used to select the change overcharacter. Defaults to
<CTRL-Z> ($1A)
Special Function Characters embedded in transmitted text:
<CTRL-B> Sends your AAB string as a HERE-IS message
<CTRL-D> Stops sending when the transmit buffer is empty
<CTRL-E> Sends a "Who Are You" request to the other station
<CTRL-F> Same as CTRL-D but sends your callsign in Morse
<CTRL-T> Sends the TIME if the DAYTIME clock has been set
<CTRL-Z> Changes your PK-232 from send (ISS) to receive (IRS).
11.7.1 ARQ Break-In (ACHG Command)
In the linked or connected mode, (ARQ), when you're the "Information Receiving Station,"
you can use the "ACHG" command to interrupt the distant station's comments.
As the "Information Receiving Station," you normally rely on the distant station to send
the "<CTRL-Z>" to "change-over" at the end of his comments. ACHC is a command that
forces both systems to reverse the "Information Receiving" and "Information Sending"
status of the link.
o Use the ACHG command only when really needed to interrupt the distant station.
11.7.2 Entering Your Auto-AnswerBack (AABI)
Timewave Pactor allows you to request the identity of the station you are conversing with
by sending your PK-232 a <CTRL-E>. This causes the PX-232 to send an inquiry Who aRe
YOU (WRU) request to the other station.
For this reason, you should set your own Auto-AnowerBack (AAE) message to "DE YOUR-
CALL". Your PK-232 will automatically send the AAB message when another station re-
quests your identity, and then stop sending.
11.7.3 Operating Pactor with Other Modem frequencies and Shifts
All Pactor operation uses 200 Hz shift PSK tones as does HF Packet.
