INT14 waiting for character
Hello.

Unfortunately, while what you say rings true
(I could find the keyboard wait inbios.S) doing anything about it is vastly non-trivial to me.
Please have a look into a rombios.c of the Bochs. That subfunction is 14 lines of a C code only and is absolutely straight-forward (although you'll have to do it in asm).

Isn't this (wait for character on
serial port) required for lots of DOS programs?
No idea, but I have none of those for example. The programs I have, are either using fossil, or the direct access. int14 have too many limitations so it is not in a wide usage I think.

Is anyone with
knowledge of the internals interested in implementing it? I hope so.
At least you can try to motivate them. Submit an RFE on SF, attach the example program that uses that functionality (and therefore doesn't work under dosemu) etc. I don't think developers will be motivated to do that without you trying hard to motivate them, but who knows:)
