I have built my own RS-232 converter. An IC, two resistors and
a diode did the trick. This only works when your modem accepts TTL
level voltages. If is doesn't your interface becomes a little bit
more complicated.

Yes, but you need some extra software. Recently such a program was posted
to this group. It would make the C64 able to handle 2400 baud.
