XStream‐PKG‐U™ USB RF Modem – Product Manual v4.2B5 [2006.02.27]
FL (Software Flow Control) Command
FT (Flow Control Threshold) Command
GD (Receive Good Count) Command
HP (Hopping Channel) Command
<Serial Interfacing> FL Command is used to
configure software flow control. Hardware flow
control is implemented with the XStream Modem
as the DO2 pin (
serial data can be transferred to the modem. FL
Command can be used to allow software flow
control to also be enabled. XON character used is
0x11 (17 decimal). XOFF character used is 0x13
(19 decimal).
<Serial Interfacing> Set/Read the flow control
threshold. When FT bytes have accumulated in
the DI buffer,
software flow control character is transmitted.
<Diagnostics> Set/Read the count of good
received RF packets. Parameter value is reset to
0 after every reset and is not non-volatile (Value
does not persist in the 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.
<Networking> HP Command is used to set the
modem’s hopping channel number. A channel is
one of three layers of addressing available to the
XStream modem. In order for modems to
communicate with each other, the modems must
have the same channel number since each
network uses a different hopping sequence.
Different channels can be used to prevent
modems in one network from listening to transmissions of another.
