I have some devices that are only accessible via RS-232 cables. The problem is that I have no RS-232 to USB adapters so I can't access them.
What I do have is a bunch of serial cables, most interestingly Cisco RJ45 (8P8C) to RJ45, that happen to fit in ethernet ports.
I've found this article that points out that you can use
socat (installable via Homebrew) to open a
PTY to work with serial over Ethernet, but it doesn't go into any detail on how that would work.
It also points to Multicom, but again, without any useful setup instructions.
Is using a serial cable even the correct one for Serial via Ethernet?
