Explanation
1. S is a communication port number: COM1 is number 1, COM 2 is number 2, Card 1 is number 11 and Card 2 is

number 12. If the data is out of the communication port range, the instruction does not execute any sending or
receiving.
2. If you use a specific character or characters to end receiving data, it is suggested that you apply the instruction to
ASCII data. If you do not apply the instruction to ASCII data, it is suggested that you use a timeout period to end
receiving data.
