________________________________________________________________________________
PACLen "n/n" Default: 128/128
Mode: Packet Host: PL
_________________________________ Parameters: __________________________________
"n" - 0 to 255 specifies the maximum length of the data portion of a packet.
0 - Zero is equivalent to 256.
________________________________________________________________________________
PACLEN sets the maximum number of data bytes to be carried in each packet's
"information field" on each Radio Port.
Most keyboard-to-keyboard operators use the default value of 128 bytes for
routine VHF/UHF packet services. For this reason the default is set to 128
as shown above. On HF Packet PACLEN should be reduced to 64 or less.
Your PK-900 automatically sends a packet when the number of characters you
type for a packet equals "n."
________________________________________________________________________________
PACTime EVERY|AFTER "n" Default: AFTER 10 (1000 msec.)
Mode: Packet Host: PT
_________________________________ Parameters: __________________________________
"n" - 0 to 250 specifies 100-millisecond intervals.
EVERY - Packet time-out occurs every "n" times 100 milliseconds.
AFTER - Packet time-out occurs when "n" times 100 milliseconds elapse without
input from the computer or terminal.
________________________________________________________________________________
The PACTIME parameter sets the amount of time in 100 msec increments that the
PK-900 will wait for a character to be received on the serial port before
sending a packet in Transparent Mode. The PACTIME parameter is always used in
Transparent Mode but is also used in Converse Mode if CPACTIME is ON.
When EVERY is specified, the characters you type are "packetized" every "n"
times 100 milliseconds. When AFTER is specified, the characters you type are
"packetized" when input from the terminal stops for "n" times 100 milliseconds.
The PACTIME timer is not started until the first character or byte is entered.
A value of 0 (zero) for "n" means packets are sent with no wait time.
________________________________________________________________________________
PACTOr ( PT for Short ) Immediate Command
Mode: Command Host: Pt
_______________________________________________________________________________
PACTOr is an immediate command that switches the PK-900 into the PACTOR mode
of operation on Radio Port 1.
PACTOR is a mode of data communication that combines some of the features of
both AMTOR and packet. The abbreviated command is PT. It has both a linked
mode called ARQ and a non-linked mode called unproto.
