I haven't read any other complaints about this issue here. When I use the PC keyboard with Teraterm (v4.85) on the PicoMite, I regularly get incorrect (ghost) characters like "[A" or "[B" in the text when I move the cursor keys (not very slow) across multiple lines in the editor, making this input method useless. It reminds me of incorrect input characters on the Maximite many years ago. Have others observed similar issues? Is there perhaps already a solution or explanation?

Which version of MMBasic? Any particular hardware setup? Could it be USB interrupts getting in the way? It sounds like a timing issue when reading the keyboard. I can't say I've noticed it myself but I'm not a "power user". :) I almost always simply select a block using F4.

the escape codes for PUP and PDOWN are esc [ A and esc [ B. That means somehow you are losing the esc or alternatively there is too long a pause between the esc and the [ character. Do you have a inter-character pause set up in teraterm? You shouldn't need one but play with this and see what happens. |

@Mick All versions since PicoMite was released. @Peter Thanks for the tip!  I've set a 10 ms transmission delay for years (since Maximite). I'd somehow come to terms with it. I've now set the delay to 0 ms, and everything works perfectly, as far as I can see! I'm very happy! Thanks, both of you!  Kind regards, Michael  causality ≠ correlation ≠ coincidence |

Exactly! The problem is solved! What I haven't mentioned yet, but still find surprising: The keyboard is a PEACOCK (actually Cherry) pre-PS2 AT keyboard from over 30 years ago It's connected to a Windows 7 PC. It's amazing that such a configuration still works without problems after so long.  Michael causality ≠ correlation ≠ coincidence |
