Syslinux - Nov 2019 - Request to Document obscure SERIAL flowcontrol setting

Hi:

I took me a while to figure this out, so I thought it might be good to document
on the wiki.

When using Syslinux's SERIAL option (
https://wiki.syslinux.org/wiki/index.php?title=SYSLINUX#SERIAL_port_.5Bbaudrate_.5Bflowcontrol.5D.5D
) in conjunction with Serial over LAN (
https://en.wikipedia.org/wiki/Serial_over_LAN), there is no "CTS
assertion" (at
least with some BIOS), but DTR and RTS are still needed.

I would like to request that the following line be added to the "Typical
values"
section of 
https://wiki.syslinux.org/wiki/index.php?title=SYSLINUX#SERIAL_port_.5Bbaudrate_.5Bflowcontrol.5D.5D
:

3 - 0x003 - Only assert DTR/RTS, some serial over LAN implementations

Thanks.
