uTerm (micro-Term) is a VT100-like terminal for the Z80-MBC2 (https://hackaday.io/project/159973). It has a VGA out and PS/2 keyboard connector, a power supply for the Z80-MBC2 and a "transparent" serial-USB port.
This fork of https://github.com/SuperFabius/uTerm was originally made for supporting German Keyboard-Layout. Then, I recognized, that some kind of keyboards with PS/2 doesn't react at the given firmware. They are just sending out 0xAA all the time and no key codes. By comparing the signals to a system, where they are working fine, I found that they need a reset (0xff), to work propperly. This fork solve therefore three things:
- the state machine for the keyboard has been changed to support this kind of keyboards, which are waiting for reset.
- the right alt key is now used as a separate modifier to support the ALTGR-Codes on many non US-Keyboard-Layouts.
- the keys are changed corresponding to German Layout
To compile this code, I used Keil µVision5 under Windows X!
I further added the code for using an ESP8266 for using telnet via WiFi.
Here comes the original Text:
These are the sources modified for the uTerm forked from the Madis Kaal repository (forked from the original repository of K. C. Lee: https://github.com/FPGA-Computer/STM32F030F4-VGA. Original project page: https://hw-by-design.blogspot.com/2018/07/low-cost-vga-terminal-module-project.html)

NOTE: I've updated here only the changed source files, so you must recompile all to get the new executable.
Supported uTerm boards:

- A071218-R290319
Supported uTerm-S boards:
- A200419
UPDATE (11/2019): Solved a bug (by gkaufman) using the right CTRL key in some situations (i.e. CTRL-L)

font conv/
-
source code + Windows console executable for a font conversion program. It imports GLCD font Creator file and converter it to a C font table of the comverted scan line bitmaps that is to be used with the VGA library.

The converter is compiled using Pelles C http://www.pellesc.de/index.php?page=start&lang=en
