[syslinux] no kbd via serial

I had an isolinux config that was working with Kontron CG2100s for 
serial console with console redirection enabled in the BIOS (and 
attaching via SOL through an Intel RMM3 module) - for some reason I had 
to set serial port 1 instead of 0 in the config (even though the 
physical port is 0, and the RMM is supposed to just be redirecting the 
physical port), but it worked.

A tester on a different box (same model and configuration) that didn't 
have console redirection enabled complained that they couldn't see the 
boot menu; I tried changing the serial port back to 0 in the isolinux 
config, and now the menu is visible, but it doesn't respond to keyboard 
input (again, over SOL; I haven't tried physical serial).  This turns 
out to be true (menu visible, no response to kbd) whether serial 
redirection is enabled or not.

Has anyone encountered anything similar, and/or have any tips for what 
else to try?
