Specifications

________________________________________________________________________________
8Bitconv ON|OFF Default: OFF
Mode: Packet, PACTOR, ASCII Host: 8B
_________________________________ Parameters: __________________________________
ON - The high-order bit IS NOT stripped in Converse Mode.
OFF - The high-order bit IS stripped in Converse Mode.
________________________________________________________________________________
8BITCONV permits packet and ASCII transmission of 8-bit data in Converse Mode.
When 8BITCONV is OFF (default), the high-order bit (bit seven) of characters
received from the terminal is set to 0 before the characters are transmitted.
________________________________________________________________________________
AAb text Default: empty
Mode: Baudot, ASCII, AMTOR, PACTOR Host: AU
_________________________________ Parameters: __________________________________
text - Any combination of characters up to a maximum of 24 characters.
________________________________________________________________________________
Use the AAB command to enter an acknowledgment text for Baudot, ASCII and AMTOR.
AAB sends automatic confirmation in Baudot, ASCII and AMTOR in response to a
distant station's WRU? request. Set WRU ON to activate Auto-Answerback in
ASCII and Baudot. In AMTOR and PACTOR, UserBIT 9 (UBIT 9) controls the Auto-
Answerback feature.
Type "AAB (24-character text)" to store your AnswerBack in memory.
________________________________________________________________________________
ABaud "n" Default: 110 bauds
Mode: ASCII Host: AB
_________________________________ Parameters: __________________________________
"n" - Specifies the ASCII data rate or signaling speed in bauds from your
PK-900 to your radio.
________________________________________________________________________________
ABAUD sets the radio ("on-air") baud rate only in the ASCII operating mode on
Radio Port 1. This value has no relationship to your computer or terminal
program's baud rate. The available "n" ASCII data rates in bauds are:
45, 50, 57, 75, 100, 110, 150, 200, 300, 400, 600, 1200, 2400, 4800 and 9600

AChg Immediate Command
Mode: AMTOR, PACTOR Host: AG
________________________________________________________________________________
ACHG is an immediate command used in AMTOR and PACTOR by the receiving station
to interrupt the sending station's transmissions.
As the receiving station, you usually rely on the distant station, your part-
ner in the ARQ "handshake", to send the "+?" or PTOver command to do the
changeover. However, in ARQ (Mode A), or linked PACTOR, you can use the ACHG
command to "break in" on the sending station's transmission. Use the ACHG
command only when it is needed.
