Timewave PK-900, Operating Manual, Page: 278 / 392

________________________________________________________________________________
TXdelay "n/n" Default: 30/30 (300 msec.)
Mode: Packet, Baudot and ASCII Host: TD
_________________________________ Parameters: __________________________________
"n" - 0 to 120 specifies ten-millisecond intervals.
________________________________________________________________________________
The TXDELAY command tells your PK-900 how long to wait before sending packet
frame data after keying your transmitter's PTT line. All transmitters need some
amount of start-up time to put a signal on the air. This parameter should be
set separately for Radio Port 1 and Radio Port 2 since it is unlikely that the
radio transmitters on each port will require exactly the same amount of key-up
time. The default value of 300 msec is a good starting point should work with
almost all transceivers.
In fact many of the newer transceivers can use smaller TXDELAY values. Crystal
controlled transceivers can often use smaller values as well. On the other
hand, tube-type transceivers and amplifiers can require a longer time to switch
and may require TXDELAY to be increased. Experiment with the value to determine
the shortest setting you can use in reliably in Packet.
Baudot and ASCII use TXDELAY between PTT ON and the start of transmitted data.

TXFlow ON|OFF Default: OFF
Mode: Transparent Host: TF
_________________________________ Parameters: __________________________________
ON - Software flow control for the PK-900 is active in Transparent Mode.
OFF - Software flow control for the PK-900 is disabled in Transparent Mode.
________________________________________________________________________________
When TXFLOW is ON, the setting of XFLOW determines the type of flow control used
in Transparent Mode by the PK-900 to control TRANSMITTED data.
When TXFLOW is OFF, the PK-900 uses only hardware flow control to control
TRANSMITTED data; all data sent to the terminal remains fully transparent.
When TXFLOW and XFLOW are ON, the PK-900 uses the Start and Stop characters
(set by XON and XOFF) to control the input from the computer.
________________________________________________________________________________
TXRev ON|OFF Default: OFF
Mode: All Host: TX
_________________________________ Parameters: __________________________________
ON - Transmit data polarity is reversed (mark-space reversal).
OFF - Transmit data polarity is normal.
________________________________________________________________________________
Use the TXREV Command to reverse the mark and space in the transmitted AFSK and
FSK signals.
In some cases, the station you're working may be receiving inverted data
although it is transmitting in correct polarity. Set TXREV ON to reverse the
sense of your transmitted signals.
