Timewave PK-232 MBX, Руководство по эксплуатации, Страница: 233 / 266

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

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

TXdelay "n" Default: 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-232 how long to wait before sending packet
frame data after keying your transmitter's PTT line (default 300 msec).
All transmitters need some amount of start-up time to put a signal on the air.
The default value of 300 msec 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.
