oo16550 highspeed

I see references to the highspeed serial buffering (isr16550) and I
understand how it works.
The docs say you can use it (link it) with the ser16550 driver.
Is this also available/included for the oo16550? Is the high speed ISR in
there by default?
I looked at the code and can't tell. The sources for the oo16550 lib does
have an include referance that points to the isr16550 directory. If not can
I link it in? do I need to specify the two new registry entries (isrdll and
isrhandler)?

my sources uses:
SOURCELIBS= \

$(_COMMONOAKROOT)\lib\$(_CPUINDPATH)\com_mdd2.lib \

$(_COMMONOAKROOT)\lib\$(_CPUINDPATH)\oo16550.lib \

$(_COMMONOAKROOT)\lib\$(_CPUINDPATH)\serpddcm.lib

Does this mean my seral is not as good (fast) as it could be?

The oo16550 does support Isr16550.
Take a look at
$(_WINCEROOT)\PUBLIC\COMMON\OAK\DRIVERS\SERIAL\oo16550\pddisr.cpp

I understand it does support isr, does it support the highspeed double
buffering feature in the ISR?

Yes, it support the double buffering that shared memory with the ISR.
