termio.h hello world

[Rafael Berkvens]

Hi all

I'm trying to understand the termio.h header file. However, all information I find is quite old and everything seems to happen in C code instead of C++. Is there any modern way to communicate with a serial link?

The termio.h c_cflag field also specifies CBAUD to a maximum of 38400, which would be too low for my program.

TL;DR: how to use termio.h, or is there a modern alternative?

Thanks for considering!

I believe termios.h is the "new" alternative to termio.h, although termios.h is still older than me. The question is, what do you actually want to do?

[Rafael Berkvens]

Indeed, I found that I'm able to use termios.h as well.

I need to communicate with a laser range finder. There's certain packages I need to sent to log in, set measurement options, or to actually receive measurements. Then, I need to capture the replies and interpret them.

I believe my best option is trial and error; luckily I have a sample of the driver for the Ethernet connection. So all I really need to know is the best practice of sending and receiving information over a serial cable.

In that case - I doubt you'll find anything that's not written in C (low level stuff like this usually is). And unless the world of serial io changed a lot in the past 2 decades, you may not find anything much more recent than this. The maximum set for the baud rate shouldn't pose too much of a problem, you can probably extend it.

I am by no means an expert (or even knowledgeable) in this field, so take what I say with a grain of salt.

I've been communicating to scanning laser range finders in C++ using boost.asio just fine. No need to resurrect ancient non-portable technologies.

Waw, this Boost.Asio is indeed exactly what I needed! Since the project already uses Boost.Random, there shouldn't be a problem including this. Thank you!

[hanst99]

Boost.Asio. Of course. Damn, and I just read through most of the boost stuff the other day.

Haha, no problem, I'm there now. I've got this marked as solved, thanks for the help.
