I just tried c2nload'ing 65535 bytes of random data to a VIC-20 and to a C128
in both modes.  I had modified the loader so that it keeps the high address
constant, and I loaded the data to the screen memory.  There were no problems,
neither with Debian GNU/Linux on an IBM Thinkpad A20m nor with Microsoft
Windows 98 on a Compaq Presario 5441, when the 16550 FIFO was enabled and
the receive and transmit buffers were set to 3/4 and 4/4 of the maximum,
respectively.  (I don't know if the buffer sizes matter.)

So, if changing the serial port settings doesn't work, I unfortunately cannot
help you further.  The code is open source and should compile on anything
that supports Win32 (I've used GCC from  Of course,
patches are appreciated.
