This may be implementation specific, but have you tried setting $| to some non-zero value? Per the Camel book (and other sources such as perldocs):

If set to nonzero, forces an fflush(3) after every write or print on the currently selected output channel.

I haven't tested it in the context of telnet, but it might be worth giving it a whirl.

Good luck.
