FL (Software Flow Control) Command
FS (Forced Synch Time) Command
FT (Flow Control Threshold) Command
GD (Receive Good Count) Command
<Serial Interfacing> The FL command is used to
configure software flow control. Hardware flow
control is implemented with the modem as the
GP01 pin (CTS pin of the OEM RF module), which
regulates when serial data can be transferred to
the modem.
FL Command can be used to allow software flow
control to also be enabled. The XON character
used is 0x11 (17 decimal). The XOFF character
used is 0x13 (19 decimal)
<RF Interfacing> The FS command only applies
to streaming data. Normally, only the first packet
of a continuous stream contains the full RF initial-
izer. The RF 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.
<Serial Interfacing> The FT 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 soft-
ware flow control character is transmitted.
<Diagnostics> The GD 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 modem'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 modem is reset.
The GD parameter is not reset by pin, serial port or cyclic sleep modes.
