fossil_send_break
Send break void fossil_send_break ( int port, FOS_BREAK_SIZE break_size ); Parameters
port
- Port specifier: FOSSIL_EXT = 0 for EXT port,
FOSSIL_COM = 1 for COM port
break_size
- Enumeration type:
FOS_LONG_BREAK = 1, long break
FOS_SHORT_BREAK = 2, short break
FOS_EXTRALONG_BREAK = 3, extra long break
Return Value
- -- none --
Comments
- A short break is a continuous Low on the TXD output for a duration of
more than one frame transmission time M, where:
M = startbit + data bits (+ parity bit)+ stop bit
A long break is a continuous Low on the TXD output for a duration
of more than two frame transmission times plus the transmission
time for three additional bits (2M+3).
A extra long break is a continuous Low on the TXD output for a duration
of more than three frame transmission times.
