This could mean that the com port read routine is getting garbage from
the serial port, which the bootloader assumes comes from you pressing
a key to stop the boot.

It could be that your hardware returns junk characters when a byte is read
with nothing hooked up.  You should build a biosboot_com0 with the 
'-DDIRECT_SERIAL' option disabled and see if that helps.
