Soft_Uart_Read

Prototype	unsigned short Soft_Uart_Read(unsigned short *error);
Returns	Returns a received byte.
Description	Function receives a byte via software UART. Parameter error will be zero if the
	transfer was successful. This is a non-blocking function call, so you should test the
	error manually (check the example below).
Requires	Soft UART must be initialized and communication established before using this func-
	tion. See Soft_Uart_Init.
Example	// Here’s a loop which holds until data is received:
	do
	data = Soft_Uart_Read(&error);
	while (error);
	// Now we can work with it:
	if (data) {...}

Soft_Uart_Write

Prototype	void Soft_Uart_Write(char data);
Description	Function transmits a byte (data) via UART.
Requires	Soft UART must be initialized and communication established before using this func-
	tion. See Soft_Uart_Init.
	Be aware that during transmission, software UART is incapable of receiving data – data
	transfer protocol must be set in such a way to prevent loss of information.
Example	char some_byte = 0x0A;
	...
	Soft_Uart_Write(some_byte);
