When TRFLOW is ON, the type of flow control used by the computer RECEIVING data<br />
in Transparent Mode is determined by how START and STOP are set.<br />
When TRFLOW is OFF, only "hardware" flow control (RTS, DTR) is available to the<br />
computer RECEIVING data from the <strong>PK</strong>-<strong>232</strong> in Transparent Mode.<br />
If TRFLOW is ON, and START and STOP are set to values other than zero, software<br />
flow control is enabled for the user's computer or terminal. The <strong>PK</strong>-<strong>232</strong><br />
responds to the user START and user STOP characters while remaining transparent<br />
to all other characters from the terminal.<br />

TRIes "n" Default: 0<br />
Mode: Packet<br />
Host: TI<br />
_________________________________ Parameters: _________________________________<br />
"n" - 0 to 15 specifies the current RETRY level on the selected input<br />
channel.<br />
_______________________________________________________________________________<br />
TRIES retrieves (or forces) the count of "retry counter" on the data channel<br />
presently selected.<br />
If you type TRIES without an argument, the <strong>PK</strong>-<strong>232</strong> returns the current number of<br />
tries if an outstanding unacknowledged frame exists. If no outstanding<br />
unacknowledged frame exists, the <strong>PK</strong>-<strong>232</strong> returns the number of tries required to<br />
get an ACK for the previous frame.<br />
If you type TRIES with an argument the "tries" counter is forced to the entered<br />
value. Using this command to force a new count of tries is not recommended.<br />

TXdelay "n"<br />
Default: 30 (300 msec.)<br />
Mode: Packet, Baudot and ASCII<br />
Host: TD<br />
_________________________________ Parameters: _________________________________<br />
"n" - 0 to 120 specifies ten-millisecond intervals.<br />

The TXDELAY command tells your <strong>PK</strong>-<strong>232</strong> how long to wait before sending packet<br />
frame data after keying your transmitter's PTT line (default 300 msec).<br />
All transmitters need some amount of start-up time to put a signal on the air.<br />
The default value of 300 msec should work with almost all transceivers.<br />
In fact many of the newer transceivers can use smaller TXDELAY values. Crystal<br />
controlled transceivers can often use smaller values as well. On the other<br />
hand, tube-type transceivers and amplifiers can require a longer time to switch<br />
and may require TXDELAY to be increased. Experiment with the value to determine<br />
the shortest setting you can use in reliably in Packet.<br />
Baudot and ASCII use TXDELAY between PTT ON and the start of transmitted data.<br />
