SerialPort

Fields

handle :: Handle

timeout :: Int

hOpenSerial

Arguments

:: String

The filename of the serial port, such as /dev/ttyS0 or /dev/ttyUSB0

-> BaudRate

-> Word8

The number of bits per word, typically 8

-> StopBits

Almost always One unless you're talking to a printer

-> Parity

Error checking

-> FlowControl

-> IO Handle

Open and configure a serial port and return a Handle

openSerial

Arguments

:: String

The filename of the serial port, such as /dev/ttyS0 or /dev/ttyUSB0

-> BaudRate

-> Word8

The number of bits per word, typically 8

-> StopBits

Almost always One unless you're talking to a printer

-> Parity

-> FlowControl

-> Int

Receive timeout in milliseconds

-> IO SerialPort

Open and configure a serial port

recvChar :: SerialPort -> IO (Maybe Char)

Possibly receive a character unless the timeout given in openSerial is exceeded.

sendChar :: SerialPort -> Char -> IO ()

Send a character

closeSerial :: SerialPort -> IO ()

Close the serial port
