Everything is working very well with the PSXserial client. 100% success on EXE execution, and the reset functionality works perfectly and is very useful. Just console mode to finish and thats it.
Currently on with :-
- Flashrom on PSone - so the PSXserial can load instantly from ROM using romboot/romprod. See here http://www.psxdev.net/forum/viewtopic.php?f=24&t=3392
- Set-up ESP8266 toolchain. I am going to fork the source for ESP link , and make some adjustments to the web interface so its more suited to this application, scope out adding extra GPIO control for future use
