All but the very old UUCP packages I've seen (DECUS UUCP) will run over
TCP/IP.

As long as you can get a login prompt. There's a project, tty0tty. This
makes a virtual null modem cable on Linux. Using this, you can connect a
system that doesn't use IP UUCP to one that does, running under
emulation, allowing that machine to be reachable by the others.

; vax8650.ini: 
; Linux (agetty) listens via /dev/tnt0, VMS (simh) grabs /dev/tnt1.
; This is for VMS to dial into Linux.
; Linux can dial in via /dev/tnt2, into VMS /dev/tnt3.
; DECUS UUCP uses TXA0 to call *into* Linux.
; Taylor UUCP (from Linux) calls *out* and connects to TXA1
; Non-UUCP logins work as well, providing they are on the correct port.

You can probably also tether a smartphone, and use that like you'd have
used a modem before. I've not run UUCP over it, but I have used it to
dial into places. Should the internet go down, you could still connect
one system to another using that.
