Has anyone tried VT100 control codes on minicom? Before I start testing, I thought I'd ask if anyone else has already tried this?

Not sure what you are asking, Curbie. I use minicom as a console for my homebrew Z80 and 680x0 systems (Cromemco too). I thought that the default for minicom was VT100 (or is it ANSI? ... don't know that there is much of a difference WRT the things I use it for). All the applications that I use are configured for VT100/ANSI, and they work fine.

Hi Roger,

Control codes for terminals (like the VT100) are terminal functions accessed by user programs, that do things like clear screen, cursor home, cursor return, cursor up/down/left/right/, lock or unlock keyboard, erase to end of line/screen, low/normal intensity, position cursor... The minicom default is VT102 (almost same), question is does minicom's implementation of the VT102 emulation include Control codes for theVT102?

vt100.c has a state machine to interpret "vt102" escape sequences and windows.c outputs translated escape sequences that match your controlling terminal's emulation using the "TERM" environment variable.

It claims:

 *              It's not a "real" vt102 emulator - it's more than that:
 *              somewhere between vt220 and vt420 in commands.

Thanks Mike,

I'll need to write some more library routines to test cursor positioning codes, but I'll go on that.

Thanks,

Curbie
