I am surprised that, thus far, noone has mentioned 'rz' (rx, rb, ...),
which can be passed a "-1" flag specifying that standard output be used
for the transfer.  The initial help screen mentions that this option is
for use under 'cu'.  Since rz uses standard io, this obviates the need
to directly access a tty line, and the problems mentioned above.
