Please don't hit me...
Did you translate the character from zeddy to ASCII?
Or is this automatic in ZXPand+?
What happens if you send the same character multiple times?
Always the same result or differs the result periodically?
Kind regards Paul
In theory, there is no difference between theory and practice. But, in practice, there is.

@Paul Turns out the problem is with my TTL/RS232 voltage converter so the signals aren't detected correctly. I'll get a new one and hope my Zxpand didn't melt. :)

Thanks for your input though. I'll report here when I have news.

Hey all,
I just wanted to let you know that I replaced my serial cable and now sending to the ZX works fine (LOAD "$" works great, but there's no LOAD "$ STOP" :) ).

Next step is to try the SERIAL GET command soon and then rule the world. :)
