Specifications

UARTs
initUart(uartNum, bps)
Enable UART at specified rate (zero rate to disable)
initUart(uartNum, bps, dataBits, parity, stop)
Enable UART at specified rate (zero rate to disable), data bits,
parity, and stop bits
flowControl(uartNum, isEnabled)
Enable RTS/CTS flow control. If enabled, the CTS pin functions
as a “Clear To Send” indicator
flowControl(uartNum, isEnabled, isTxEnable)
Enable RTS/CTS flow control. If enabled and parameter
isTxEnable is True, then the CTS pin functions as a TXENA
(transmit enable) signal. If enabled and isTxEnable is False, then
the CTS pin functions as a “Clear To Send” indicator
Note: uartNum is 0 or 1 on most platforms. Some platforms will have only UART0 available.
