Detailed Description

Commonly used modbus host operation functions.

   The API form is as follows:
   - agile_modbus_serialize_xxx    package request data
   return value:
       >0: Request data length
       Others: Abnormal

   - agile_modbus_deserialize_xxx  parses response data
   return value:
       >=0: The length of the corresponding function code response object (such as 03 function code, the value represents the number of registers)
       Others: exception (-1: message error; others: exception code can be obtained according to `-128 -$return value`)
