SR_EVEN_PAR" means 7 bit character length, 2 stop bits and even parity (see Example). An example in
BASIC Syntax: "SR_7BIT Or SR_2STOP Or SR_EVEN_PAR".
The user supplied buffer must be available the whole time the serial interface is working. Since after
leaving a function the local variables are no longer available, it is most times a good idea to provide the
user supplied buffer as a global variable.
Please use Serial_ReadExt() if you work in serial IRQ mode. Serial_Read() only supports polled
mode.
Parameter
serport interface number (0 = 1st serial port, 1 = 2nd serial port, ...)
ramaddr address of the buffer
recvlen size of receive buffer
sendlen size of send buffer
par interface parameter (see par table)
