Introduction

This module defines the following constants:

• UDP = 0; UDP protocol

• TCP = 1; TCP protocol

• RAW = 0; RAW data format for read/write operations

• BCD16 = 1; BCD16 data format for read/write operations
• BCD32 = 2; BCD32 data format for read/write operations
• BIT = 3; Boolean data format for read/write operations
• INT16 = 4; INT16 data format for read/write operations
• INT32 = 5; INT32 data format for read/write operations
