I have not seen an RS232 interface in the last few years that is
capable of less than 4800 baud.  The electronics normally used for C64
interfaces are generally capable of 19,200 bps and even higher rates.
Consistently.

The problem is much more likely to be that the software on the 64
cannot handle 2400 baud.  We all know that the 64 messes up at 1200,
but a software patch is included with just about every modem program.
This patch doesn't work so hot at 2400 baud, but there are new and
enhanced RS232 drivers that will work.  Because of this problem, I
usually end up running both of my Courier 2400 modems at 1200 baud.
