I don't know what TRF is, but when I owned a BNS, I used a
pair of tools named rb and sb. They are in a package named lrzsz.
The package may be named something slightly different by your distro.
Anyway, sb sends files via ymodem to the unit, and rb receives files.
The lrzsz suite includes similar programs for the xmodem and zmodem protocols.
All are documented by manpages, and usage is straightforward.
They work well with shell accounts, too. That was my earliest means
of Internet access: a BNS connected to a remote Unix box, via a 2400 baud
