示例2: LOCK_MUTEX

/*!
\fn ulong Win_QextSerialPort::lineStatus(void)
returns the line status as stored by the port function.  This function will retrieve the states
of the following lines: DCD, CTS, DSR, and RI.  On POSIX systems, the following additional lines
can be monitored: DTR, RTS, Secondary TXD, and Secondary RXD.  The value returned is an unsigned
long with specific bits indicating which lines are high.  The following constants should be used
to examine the states of individual lines:

\verbatim
Mask        Line
------      ----
LS_CTS      CTS
LS_DSR      DSR
LS_DCD      DCD
LS_RI       RI
