| This program was created during and for Vactanilad | |
| It drives the stepper motors using ethernet connection to GSI network (TCP protocol) | |
| Useful commands: | |
| @ - start of the command: @03 | |
| 0 - number of machine | |
| @03 - initialize both axis, X and Y | |
| R,r - return to 0 | |
| A,a = move to absolute coordinate IN STEPS |
