ClickSerialPortTransmit

Data in dataArray is transmitted onto the virtual port virtualPortId.

LIBRARY – click500serial.lib

SYNTAX –

int ClickSerialPortTransmit( int virtualPortId, int numBytes,
char* dataArray );

PARAMETER1 – The virtual port to transmit the data onto.

PARAMETER2 – The number of bytes to transmit. The maximum number of bytes is

256. If numBytes is greater than 256, only the first 256 will be transmitted. When trans-

mitting at slower baud rates you may need to delay between calls to ClickSerialPort

transmit in order to prevent overrunning the tx buffers.

PARAMETER3 – The location where the data to be transmitted is stored.

RETURN VALUE – 0 - Success/1 – Failure
