Method Details

provisionSerialDevice

default InternalSerialDeviceInterface provisionSerialDevice(String deviceFilename,
int baud,
SerialConstants.DataBits dataBits,
SerialConstants.StopBits stopBits,
SerialConstants.Parity parity,
boolean readBlocking,
int minReadChars,
int readTimeoutMillis)
                                                     throws RuntimeIOException

Provision a serial device.

Parameters:

deviceFilename - The O/S name of the device, e.g. "/dev/ttyUSB0"

baud - Baud rate

dataBits - Number of data bits

stopBits - Number of stop bits

parity - Parity option

readBlocking - Do read operations block?

minReadChars - The minimum number of characters to read

readTimeoutMillis - How long a read operation waits for data before timing out. 0 == no timeout

Returns:

Serial device instance

Throws:

RuntimeIOException - if an error occurs
