If you have set the same baudrate, databit, stopbit and parity in both ends.
And connected TXD, RXD right in the connectors it could be the Hyperterminal.

It has a nice feature that after changing the communication parameters,
you have to do disconnect and connect again for get the parameters working.
You can also save the session, restart the program.

If you used the cable with your printer, it might be that your HC11 is the DTE and and the printer is the DCE end. Once you connect it to the PC, both are DTE. This means that TX circuit is connected to TX circuit and likewise for the other circuits.
If this is indeed the problem, what you need to do is to use a cross-cable, or if you use just the TX and RX circuits, simply cross those.

Or just simply check if hardware handshaking is set :)

(It shouldn´t)
