There is documentation about the serial parameters in section 5.3 "Boot
Parameters", but there isn't documentation about how to get the boot
menu to appear on the serial console. I guess the reason is that it
varies a lot depending on the device. I guess the bootloader (syslinux
in your case) simply uses what the Bios tells, and maybe the Bios
actually tells it that a videocard exists, and thus syslinux emits it on
the video card.
At any rate, I don't think the manual can document how all these various
devices can be made to show the boot menu on the serial port, and what
would be at best missing is a fix in syslinux to behave the proper way,
be it circumventing the Bios or not, thus reassigning.
