TRFLOW {ON | OFF}
default OFF
This command allows the TNC to respond to software flow control from the computer
while in the Transparent Mode. When TRFLOW is OFF, software flow control is not
used in the Transparent Mode. Hardware flow control will be expected from the
computer by the TNC. The computer program needs to use hardware flow control, and
the RS232 cable needs to be wired with CTS and RTS connected. When ON, software
flow control is enabled and the START and STOP characters are sent by the computer
to the TNC to control the flow of data. When START and STOP are set to $00,
hardware flow control must be used. If not zero, the TNC will respond to the computer's
START and STOP characters, and remain transparent to other characters from the
terminal or computer for flow control.
When START and STOP are set for software flow control (normally <Ctrl+Q> and
<Ctrl+S>) all characters can be received in Transparent Mode (including the START
and STOP characters) by setting TRFLOW ON and TXFLOW OFF. You will not,
however, be able to send the START and STOP characters, since the TNC will interpret
them as flow control.

TRIES [n]
The TRIES command will display and optionally set the number of attempts, which have
been made to re-send a packet (on the current stream) which failed to reach its
destination. For instance, if RETRY is set to 10, TRIES will show how many attempts
have already been made to pass the data. For example, if TRIES were to show 8,
―TRIES 3‖ would reset the counter to make the TNC believe that it had only tried 3 times
so far, thus allowing 7 more attempts before the RETRY limit is exceeded.

 TXDELAY n
default 30
This command sets the transmitter key-up delay as 10*n ms. This setting establishes
the time delay between the application of push-to-talk and the start of packet data to the
transmitter. Flags (characters to begin packet) are sent during the delay. This command
needs to be set long enough to give your transmitter time to come to full power before
data is sent. If set too short the beginning of the packet will be chopped off and another
station will never be able to decode you. If set too long, additional flags at the beginning
(heard as a repetitive sound) waste air time. It may be necessary to increase your
TXDELAY to allow the receiving station sufficient time to switch from transmit back to
receive to detect your signal.
