rs-232

I'm having trouble getting a serial port to work in FreeBSD 13.1-RELEASE-p3 GENERIC. I've tried three different configurations. 1) I borrowed a USB-to-RS232 adapter from my employer and it works. It has no brand name or model number printed on it, but FreeBSD detects it just fine: ugen3.2...

Is there any simple way of forwarding a serial port over Ethernet? Thanks for ideas!
