1.  Overview

Yacer easy-HDLC is a free software tools that is very easy to use. Based on UDP, it’s debugging and testing HDLC communication equipment.

Functional and practical and simple enough to help engineers to complete debugging HDLC protocol communication task efficiently.

Features：

●  Manual input or generate random HDLC frame data

●  Calculate and display CRC checksum of manual input HDLC frame

●  Regularly or manual sending HDLC frame

●  Receiving HDLC frame, displaying in HEX or binary

●  Comparing sending and receiving data

●  Real time saving send/receive data

2.  Working principle

Computer is connected to the protocol converter by the Ethernet interface, enable serial to UDP and UDP to serial function of protocol converter.

Start easy-HDLC in the computer, it can generate HDLC frame and send to protocol converter by UDP packets. Then send out through the specified Synchronous serial port. Also, easy-HDLC receives HDLC frame from serial port by receiving UDP packets, displays, records and analyzes received HDLC frame data.

In the same computer, you can run multiple easy-HDLC instances. So you can debug multiple serial ports or multiple equipment at the same time
