Hello Albert Chin-A-Young. Let me extend the customary welcome to LQ.
I got out of Industrial Electronics in 2006. Even then, industrial electronics was the only remaining use for RS232. The efficient way to go even back then was to have an RJ45 network connection between the slow antique industrial stuff and faster machines used elsewhere.
You asked about two part numbers, presumably belonging to some manufacturer? You might know what they refer to, but I don't. It hardly stands to reason that a manufacturer will make two identical items under different part numbers, does it? Generally, later models in a Series generally improve on the specs of earlier models, like in cars. But that sort of homework you can do yourself. All of the software for Industrial stuff is usually windows binaries anyhow. This is LQ = Linux Questions.
Just looking at the software on your driver, it's legacy all right. Antique, in fact. I don't know what your problems are, but all of those systems are well past EOL. That makes it difficult if anything is required except the base OS. With linux, programs compiled against a newer version of glibc will simply refuse to run on the earlier version. And from personal experience, there was a significant revision of kernel headers between kernels 4.x.x & 5.x.x, so that makes every compile a messy one. If you’re a linux newbie, this is a nightmare.
Ask your boss (I presume it’s some business thing) what he wants to throw money at. Does he want to throw money at propping up whatever obsolete 20th century thing that’s broken now? Or does he want to replace it now? Neither option may be quick, and he probably has pressing production issues. But next time, throwing money at old crap will probably not be a viable option. It may not be viable now, although I’ll guess it gets you going.
