var ( // The list of standard baud-rates. StandardBaudRates = map[uint]bool{ 50: true, 75: true, 110: true, 134: true, 150: true, 200: true, 300: true, 600: true, 1200: true, 1800: true, 2400: true, 4800: true, 7200: true, 9600: true, 14400: true, 19200: true, 28800: true, 38400: true, 57600: true, 76800: true, 115200: true, 230400: true, } )
Functions ¶
func IsStandardBaudRate ¶
IsStandardBaudRate checks whether the specified baud-rate is standard.
Some operating systems may support non-standard baud-rates (OSX) via additional IOCTL.
func Open ¶
func Open(options OpenOptions) (io.ReadWriteCloser, error)
Open creates an io.ReadWriteCloser based on the supplied options struct.
Types ¶
type OpenOptions ¶
type OpenOptions struct {
// The name of the port, e.g. "/dev/tty.usbserial-A8008HlV".
PortName string
// The baud rate for the port.
BaudRate uint
// The number of data bits per frame. Legal values are 5, 6, 7, and 8.
DataBits uint
// The number of stop bits per frame. Legal values are 1 and 2.
StopBits uint
// The type of parity bits to use for the connection. Currently parity errors
// are simply ignored; that is, bytes are delivered to the user no matter
// whether they were received with a parity error or not.
ParityMode ParityMode
// Enable RTS/CTS (hardware) flow control.
RTSCTSFlowControl bool
InterCharacterTimeout uint
MinimumReadSize uint
// Use to enable RS485 mode -- probably only valid on some Linux platforms
Rs485Enable bool
// Set to true for logic level high during send
Rs485RtsHighDuringSend bool
// Set to true for logic level high after send
Rs485RtsHighAfterSend bool
// set to receive data during sending
Rs485RxDuringTx bool
// RTS delay before send
Rs485DelayRtsBeforeSend int
// RTS delay after send
Rs485DelayRtsAfterSend int
}
OpenOptions is the struct containing all of the options necessary for opening a serial port.
type ParityMode ¶
type ParityMode int
Valid parity values.
const ( PARITY_NONE ParityMode = 0 PARITY_ODD ParityMode = 1 PARITY_EVEN ParityMode = 2 )
