TCnSerialPort.Write(String) Method
Writes the specified string to the serial port.
public procedure Write(text: String); overload;
Parameters
- text
- Type: String
The string for output.
Use this method when you want to write a string as output to a serial port.
If there are too many bytes in the output buffer and Handshake is
set to XOnXOff then the SerialPort object may raise a
TimeoutException while it waits for the device to be ready to
accept more data.
By default, SerialPort uses
ASCIIEncoding to encode the characters.
ASCIIEncoding encodes all characters greater than 127 as
(char)63 or '?'. To support additional characters in that range,
set Encoding to
UTF8Encoding,
UTF32Encoding, or
UnicodeEncoding.
