OK, I have an intel box on the bench and loaded ipxe that was compiled with
both serial and video consoles, and note behaviors

starting with my current version:

show version reorts:
builtin/version:string = 1.0.0+ (2d6d)
there are some patches applied to the local version

echo ${esc:string}[2J  clears the screen both vga and serial, but on the
serial it leaves the prompt on the second line (due to trailing newline)
and on vga it leaves the prompt on the bottom of the screen. fast white on

the login screen is color on vga; no color, some bold on serial does not
draw background so fast.

config and menu are color on vga; no color some bold on serial and draw the
background on both so slow,

arrow keys and paste from serial do not work as documented.

Now grabbing and merging today's git:
>From git://git.ipxe.org/ipxe
   93acb5d..d644ad4  master     -> origin/master

show version now reports:
builtin/version:string = 1.0.0+ (e97ca)

Arrow keys now work, but paste only partialy works upto 16 characters are
ok then garbage.
All other behavior unchanged.

and  just for completeness, recompiling with today's master:
builtin/version:string = 1.0.0+ (d644a)
no other changes, all tests repeated.
