data = Read ( maxCount )
Read up to maxCount bytes from the port. Return data as a string. Return null if
no data or error. This method blocks until the maximum bytes are read or the
read timeout expires. Data are converted from bytes to a wide character string
by mbstowcs using the current locale. Use the SerialPort property LastError
to get additional error information.
data = ReadByte ( )
Read a single byte from the port. Return data as an integer value between 0 and
255. Return negative number if failure; -1
– failure, -2 – timeout. This method
blocks until the byte is read or the read timeout expires. Use the SerialPort
property LastError to get additional error information.
data = ReadTillByte ( maxCount, byteValue )
Read up to maxCount bytes from the port. Return data as a string. Return null if
no data or error. This method blocks until the maximum bytes are read, or a byte
with the specified integer value is read, or the read timeout expires. The
suggested technique to use ReadTillByte is to call it after the EV_RXFLAG event
is signaled through OnSerialPortEvent with desired character as the event
character. Use the SerialPort property LastError to get additional error
information.
status = SetBreak ( )
Set the break condition on the port. Suspends character transmissions and
enters the break state. Return 0 on success, non-zero for failure. Use the
SerialPort property LastError to get additional error information.
status = SetQueueSizes ( inputQueueSize, outputQueueSize )
Set the size of input and output queues. Return 0 on success, non-zero for
failure. Use the SerialPort property LastError to get additional error
information. More details can be found by searching msdn.microsoft.com with
the keyword “setupcomm”.
