Unfortunately, the C64 has a software uart and can't work at 2400
baud.  I have heard of some terminal programs that barely work at
2400 but these have seriously modified the interrupt routines.
I think the newest Punter BBS S/W has this.

Another alternative is a more conventional terminal program such
as Common Sense (comes free with 1660 and 1670 modems).  These
programs can adjust the "Baud Rate Factor".  I haven't tried this
myself, but it might work.  

1200 is already pushing the limit.  2400 is nearly hopeless.
There is no substitute for a REAL hardware UART!
