The Taylor UUCP is part of pkgsrc (started by NetBSD but supports many, many Unix system
platforms; see
pkgsrc.org ):

The Taylor UUCP package provides everything you need
to make a UUCP connection. It currently supports the 'f', 'g' (in all
window and packet sizes), 'G', 't' and 'e' protocols, as
well a Zmodem protocol, the FX UUCICO 'y' protocol, and two new bidirectional
protocols. If you have a Berkeley sockets library, it can make TCP connections. If you
have TLI libraries, it can make TLI connections. It supports a new configuration file
mechanism.
The "t" protocol was for use with TCP over the Internet.
