No.

Telnet transmits DC1's just as any other piece of wire would. The only
difference between the communications cable you ran between the HP3000 and your
terminal, back in the days when your terminals were within viewing distance of the
host, is the wire tht telnet implies can often be a heck of a lot longer.
Otherwise, there is absolutely no difference.

It's UNIX that doesn't transmit the DC1, not telnet. They simply aren't part
of UNIX's heritage. The presence of the go-ahead signals that DC1's represent
are an MPE-ism not shared by another operating system that I know of.
