See: src/distrib/i386/floppies/bootfloppy-com/Makefile

FLOPPYBOOTOPTIONS=      -o console=com0

Change that to com1.

The options are passed to installboot(8) when putting the bootloader into
the first floppy image. The man page lists the following options for
this case:

                 console=name
                             [amd64, i386] Set the console device.  name must
                             be one of: pc, com0, com1, com2, com3, com0kbd,
                             com1kbd, com2kbd, com3kbd, or auto.

                 ioaddr=ioaddr
                             [amd64, i386] Set the IO address to be used for
                             the console serial port.  Defaults to the IO
                             address used by the system BIOS for the specified
                             port.

                 speed=baud  [amd64, i386] Set the baud rate for the serial
                             console.  If a value of zero is specified, then
                             the current baud rate (set by the BIOS) will be
                             used.
