IHEX loader that can be embedded into the Profi 5E monitor ROM. The Profi 5E is an 8085 based computer primarily used in education.

To start the ihex loader, press F-E and then G to start. The display shows "_ LADE _". The symbols left and right will show a load animation during transmission.
After the transfer completed successfully, the display shows "EndE". If there was an error during transfer, the display would show "FEHLEr". When neither of those is shown, there might have been an internal error.
The first address of the ihex file will be stored to monitor ROM memory so that the G or E key will start without the need to setup the start address manually.
The transfer speed of the serial port can be configured via micro switches as documented in the Profi-5E documentation. On my system, transfer speeds up to 1200 bit/s do work reliably.
