8.12.4. Using Hexadecimal Codes
Hexadecimal codes can be inserted in the ASCII message when using:
sendMessage command: CALL /MEDIA/UART/P1:sendMessage(C00\x0D)
CALL /MEDIA/ETHERNET:tcpMessage(C00\x0D)
tcpMessage command:
udpMessage command: CALL /MEDIA/ETHERNET:udpMessage(C00\x0D)
▪ C00: the message.
\x: indicates that the following is a hexadecimal code.
