IrDA Parameters
Baud Rate:
115200, 76800, 57600, 38400, 19200, 9600, 4800, 2400
Data Bits:
7 or 8
Parity:
Even, Odd, or None
Stop Bit:
1
Flow Control:
None
Flow Control
To avoid data loss, three options of flow control are supported and done by
background routines.
1.
None: Flow control is disabled.
2.
RTS/CTS: RTS now stands for
Ready for Receiving
instead of
Request To Send
, while
CTS for
Clear To Send
. The two signals are used for hardware flow control.
Transmit
Transmission is allowed only when the CTS signal is asserted. If the CTS signal
is negated (= de-asserted) and later becomes asserted again, the transmission is
automatically resumed by background routines.
