VT100 option in menu? #2

Closed BRFud closed 1 year ago

BRFud commented 1 year ago

Hi, I've recently build a Versaterm - amazingly useful work, thank you. I was unsure why there was no VT100 setting in the menu under/Termainal Serrings/Type? I see only VT52, PETSCII and VT102/Ansi so thought I should ask.

Certainly it would be awesome to see more terminal types here as occasionally I am running into software configured to run on various Televideo terminals, Apple2 running CP/M, Osborne1, etc, which do not display correctly on Versaterm as far as I have yet discovered.

As far as I understand the VT100 commands are a subset of the VT102 commands, so selecting VT102 will also support VT100. The VT52 actually behaves differently than the VT100/VT102 for some commands, which is why it has a separate setting.

I'm not currently planning to add support for other terminals but it should be fairly easy to do so by modifying the code in software/src/terminal.c. Look at functions terminal_receive_char() to process control sequences received by the terminal and terminal_process_key() to send out sequences for special keys (if necessary).

Thank you for the clarification and pointer on how additional terminals could be implemented. Looks like there is the potential for VersaTerm to be able to support a long list of historical terminals, if someone capable is able to expend the effort coding them. Many thanks again!
