native RS232_Close(rs232);
Closes the RS232 interface
Parameter Explanation

native RS232_Write(rs232, const data{}, len);
Sends data via the specified RS232 interface

data Array that contains the data to be sent
len Number of bytes to be sent
Explanation
Return value
l
Number of processed bytes, if successful
Note: If the number of processed bytes deviates from the passed number

However, now only the data that could not be processed in the previous
function call needs to be passed here.
l
ERROR_FEATURE_LOCKED, if the specified interface on the device is
not released
