SerialPort (gb.net)

This class was designed to allow to communicate using a serial interface (usually RS-232 serial port). This class inherits from Stream class, so you can use standard streams methods to send and receive data, and to close the port.

Konstanty

Bits1	Constant used when the serial port has one stop bit.
Bits2	Constant used when the serial port has two stop bits.
Bits5	Constant used when the serial port has 5 data bits.
Bits6	Constant used when the serial port has 6 data bits.
Bits7	Constant used when the serial port has 7 data bits.
Bits8	Constant used when the serial port has 8 data bits.
Both	Constant used when the serial port has both software and hardware flow control.
Even	This constant represents an even parity for the serial port.
Hardware	Constant used when the serial port has hardware flow control.
None	This constant is used in the following cases:
Odd	This constant represents an odd parity for the serial port.
Software	Constant used when the serial port has software flow control.

Vlastnosti

CTS	Returns current status of the "Clear To Send" serial port signal, or FALSE if port is closed.
DCD	Returns current status of the "Data Carrier Detect" serial port signal, or FALSE if port is closed.
DSR	Returns current status of the "Data Set Ready" serial port signal, or FALSE if port is closed.
DTR	Returns or Sets current status of the "Data Terminal Ready" serial port signal. This value cannot be set when serial port is closed. If serial port is closed and you read this property, it returns FALSE.
DataBits	Return or set the number of data bits used by the serial port.
FlowControl	Return or set the serial port flow control.
InputBufferSize	Return the number of bytes of the internal input buffer.
OutputBufferSize	Return the number of bytes of the internal output buffer.
Parity	Returns or sets the serial port parity.
PortName	Returns or sets current serial port device path. This property can be changed only when serial port is closed.
RNG	Returns current status of the "Ring Indicator" serial port signal, or FALSE if port is closed.
RTS	Returns or Sets current status of the "Request To Send" serial port signal. This value cannot be set when serial port is closed. If serial port is closed and you read this property, it returns FALSE.
Speed	Place here communication speed in bauds, speed value must be a valid standard value allowed by the serial port driver (19200, 9600...). Be careful, as some common speed values like 38400 bauds are allowed by modems, but not by all serial port chips.
Status	Reflects the current status of a SerialPort object. It can be:
StopBits	Return or set the serial port stop bits.

Blocking	Returns or sets if the stream is blocking.
ByteOrder	Returns or sets the byte order used to read or write binary data to the stream.
EndOfFile	This property signals whether the last use of LINE INPUT reached the end of file, instead of reading a full line with an end-of-line character.
EndOfLine	Return or set the newline separator used by this stream.
Eof	Return if a stream reached its end.
Handle	Returns the system file descriptor associated with this Stream.
IsTerm	Return if a stream is associated with a terminal.
Lines	Returns a virtual object that allows you to enumerate a stream line by line.
NoShare
NullTerminatedString	Return or set if strings are null-terminated when they are serialized.
Tag	Returns or sets the tag associated with the stream.
Term	Return a virtual object that allows to manage the terminal associated with the stream.

Metoda

Clear	Clear the input/output buffers.
Open	Opens the serial port.

Begin	Start to buffer data written to the stream, so that everything will be sent when the Send method is called.
Close	Closes the stream.
Drop	Drop the data that has been buffered since the last call to the Begin method.
ReadLine	Read a line of text from the stream, like the LINE INPUT instruction.
Send	Send all the data, in one shot, since the last call to Begin.
Watch	Start or stop watching the stream file descriptor for reading or writing, after it has been opened.

Událost

CTSChange	Raised when CTS signal value changes.
DCDChange	Raised when DCD signal value changes.
DSRChange	Raised when DSR signal value changes.
DTRChange	Raised when DTR signal value changes.
RNGChange	Raised when RNG signal value changes.
RTSChange	Raised when RTS signal value changes.
Read	Raised when there is data to be read from the serial port.
