HS XMODEM C Source Library 1.1

Other features include 1024 block size vs 128, CRC vs checksum, configurable timers and retries

* HOW IT WORKS:
When user application initlialises HsXmodem library, it provides interface callbacks for the services used by Xmodem protocol module: timer management, serial transmission and reception, memory management, event callbacks. This architecture makes it easy to port Xmodem protocol module to any environment

Xmodem module handles all protocol information flow, error recovery, acknowledgements, timeouts and so on. When it is appropriate to send next block of data Hs Xmodem will get next memory block from user application. Similarly, when data has been received Hs Xmodem module will get the next block of memory from user application to store data into

As a backup or an alternative to TFTP, Xmodem is often used in embedded devices and appliances for the purpose of software or configuration upgrade or retrieval.

* FEATURES:
- Xmodem Sender and Receiver
