The older among us know to use sz/rz for that (still in the package
lrzsz). Designed to transfer binary files over channels requiring an
escape layer (plus some error correction on top).

But yes, nowadays I'd consider telnet mostly dead. The last legit
application for a long time, using the client to interact with clear
text protocol servers (http, smtp, you name them) is pretty well
served by "socat -", which uses readline to edit each line before
sending it.
