1  Damn Small Linux / DSL Ideas and Suggestions / Linux in real-time (like DOS) on: July 22, 2019, 04:03:16 AM
I made special hardware for a game that can connect to the computer via serial (rs232).

I have ordered a thin client PC that I will put Damn Small Linux on since it worked OK on my other PC.

Now I haven't quite figured it out, but there is software out there (RTlinux and RTAI) that is supposed to patch a kernel so that a priority kernel exists so that if one were to access a serial port with customized C code, all other actions stop until the critical section ends. This is what I need with my hardware because I tried my hardware with a normal slackware linux setup and I constantly got poor results at high baud rates.

Anyways, whats the best way to seemlessly install RTAI or RTlinux or anything else that would allow a serial port to be accessed real-time from within a compiled C program?

I am currently using the latest DSL distro at time of this writing.
