Se você tem um FM Towns e quer criar imagens de disco customizadas (a pior parte é o carregador IPL e corrigi-lo com a localização IO.SYS), então seus problemas acabaram. O Derek Pascarella criou uma ferramenta (q tá no github dele) pra facilitar o processo. Ela também é útil para fazer conversões de CD-ROM de

I deliberately did not clean up the terminal to make it look like it's shiny and was just used.

This terminal has been sitting idle for more than 40 years! It should look this way, Dusty old, unused almost forgotten

I have it in case I would get a kernel panic where I could only get troubleshooting information via the rs232c serial port

Are you excitable {Def Leppard}?
Do you love Amber (not Orange) monitors? Do you love the feel of CRT radiation right at your brains?

Do you love the color of a Wise terminal running at 80 by 25 columns?

I have a photograph for you, of a functioning 80x25 Wise serial terminal, a terminal so old, even in the year when we set up the internet in my country, it was considered super unique and ancient.

Are you ready for it?

Ta-da!

マイコンに搭載はUARTやUSART
それをレベル変換した結果RS-232Cとして使える

ただし、UARTとRS-232Cを同じ意味で使う場合もある

という感じ

stm32でUART通信

マイコン内での変数やらの値をPCで読むためによく使うUART通信の備忘録。厳密にいうと違います…
