| Description: |
| This module contains the main routine and some supporting |
| routines. |
| |
| In this example the input and output bytes are transfered to the |
| IO area, which is addressed by the io_byte_ptr. |
| In the case of the IM183-1 there is RAM. |
| The first byte of the input data is used as a service byte |
| for the change diag function. |
| The received user parameter data were copied to an interim buffer |
| and from this to the user diagnosis data. |
+------------------------------------------------------------------------+
| following environments are supported |
| Processor: SAB C165 |
| Compiler: BSO Tasking 80166 C Cross-Compiler, V 4.0 |
| Processor: iNTEL 8032 |
| Compiler: Keil |
