[hpoj-devel] PML multiplexing added to ptal-mlcd

[<pa...@rc...>]

Hi,

I just checked in some changes to ptal-mlcd to support PML multiplexing.
This means that it is now possible to run multiple applications
simultaneously that use PML on the same device, including xojpanel, ptal-hp,
and ptal-pml.  Currently the limit is 8 PML sessions per device, but this is
easy to change in the code if necessary.  The new "-nopml" switch for
ptal-mlcd turns this capability off, reverting to the former limit of 1 PML
session at a time.

Since this enhancement involved some tricky changes to the ptal-mlcd code
paths for channel opens and closes and for data transfer in both directions,
it could use as much testing as possible.  :-)
