Remarks

The Read command is to get the delimiter check status. [HEX] is a character in hexadecimal, with

the prefix “0x”.

The Write command is to set the delimiter check, enable or disable. [Parameter] is a character

that determines whether a delimiter character is applied —

 Parameter =0: Disable delimiter

 Parameter =1: Enable delimiter

When Parameter =1, [HEX] is a character in hexadecimal, with the prefix “0x”. For example,

“0x0d” for Carriage Return (CR).
