  dddns said  Hello Jim,

your MMCC application, I tested the Linux version, seems to send chr$(27) twice, when pressing esc in the VT-100 terminal. Is there a reason? I'm new to VT-100 and don't know if it is required for some device.

Regards


A VT-100 (and the older VT-52) uses the ESC-character chr$(27) to introduce the control codes (escape sequences) - thus the name "escape sequence".

https://vt100.net/docs/vt100-ug/contents.html

So probably to "cancel" an "escape sequence", a second ESC-character is sent which then will be passed through to the PicoMite?

Regards
