Hey everyone!

I've been programming for the PS/2 Keyboard, and then converting those codes into ASCII. But what do you do with the Enter, Backspace, Escape, and Tab keys?

While looking around the internet, I found this super interesting page:

https://www.asciihex.com/ascii-table

Besides the cool retro look of the site, I thought the history of each control character was very cool. It even tells you what it did for on typewriters!

Just wanted to share. I love history, and computer/typerwriter history is just as interesting to me.

[ BTW, the answer to the above question is: $0D, $08, $1B, and $09 ]

Thanks everyone!

Chad

Yes, references are nice to have. I've been using this one for years:

You output the corresponding ASCII values for them. What's the problem?

That “cool retro look” is not cool to me—terrible color choices.

That's much better...I can read it. :D

If you have a Linux box handy and need to look up the ASCII code for something, use the command man ascii.

So have I, because it's what DOS used (Code page 437) and also the Epson dot-matrix impact printers, which they still make today (and I just ordered one, to replace an ailing older one, as the new one didn't cost any more than what I was expecting to pay to get the old one fixed). I also installed the character set on my hand-held HP-71B computer,

so I could use the same printer with it as I use with the DOS machine and the workbench computer without having to run everything through a translation program.

I’m still using the manual that came with the Epson MX-80 printer I bought in 1983 (still using the printer too).
