FS (Forced Synch Time)
Command
command only applies to
streaming data. Normally, only
the first packet of a continuous
stream contains the full RF
initializer. Zlinx Radio Modems
then remain synchronized for
subsequent packets of the stream. This parameter can be used to periodically force
an RF initializer during such streaming. Any break in UART character reception long
enough to drain the DI Buffer (UART receive buffer) and cause a pause in RF data
transmission will also cause an RF initializer to be inserted on the next transmission.
FT (Flow Control Threshold)
Command
command is used to set/read
the flow control threshold. When
FT
bytes have accumulated in the
DI buffer (UART Receive), CTS
is de-asserted or the XOFF
software flow control character
is transmitted.
GD (Receive Good Count)
Command
command is used to set/
read the count of good received
RF packets. Its parameter value
is reset to 0 after every reset
and is not non-volatile (The
parameter value does not
persist in the RF module's memory after a power-up sequence). Once the "Receive
Good Count" reaches its maximum value (up to 0xFFFF), it remains at its maximum
count value until the maximum count value is manually changed or the module is
reset.
The GD parameter is not reset by pin, serial port or cyclic sleep modes.
