hi,
HP iPaq ppc having physical UART or virtual one? If physical UART, then
could you please tell me the buffer size?

regards,
hari
 
It would be better if you told us *what* you want to do, rather than asking
a number of strange questions that are obviously related to *how* you're
trying to do it...

In desktop pc, we have physical UART, i.e., 16550 16 byte buffer size. I am
asking about the existence of the same in ppc ( mainly for communication thru
COM port)

Almost certainly it uses a 16550 type UART, thus it has a 16-byte receive
FIFO. This is not the size of the buffer that is used by the serial port
driver, however (and you or I have no control over the FIFO usage, as we do
on a desktop system).

The real question is why do you want to know? Perhaps there is an issue
that doesn't involve the FIFO?

That's not documented, as far as I know. And it might be different from one
device to another. Our Windows CE devices happen to use 16550's, but that
was our choice, not a requirement for all Windows CE or Pocket PC devices.
Again, what's the *real* question? You can't possibly care about whether
it's a 16550 for no reason...
