Sending and Receiving on a Free UDP Connection with Programmed Addresses

SIn the picture (entries in hexadecimal) the following IP address is assumed: 142.11.40.35 (example only);

SFor the port address 1003, the following would be entered: for high byte: 03H;

for low byte: EBH.

SThe user data area can be up to 2048 bytes long. Up to 2042 bytes of user data can be transferred. 6 bytes are reserved for the job header.

Please note that the data length specified in the block call (LEN parameter) must include the header and the user data!
