Is this PC/SC or the drivers though ?  The Towitoko PC/SC driver for Win32
claims to release the serial port  only claim it 'on demand'.

pc/sc requires card insertion events be delivered.  So the drivers must keep
the port open.  Towitoko is technically in violation of the spec, which is
one reason I like them.

MUSCLE New PC/SC Ideas

[David Corcoran]

Hello,

I'm just finishing up a new version of pcsc-lite.  This one works
differently though.  When you start the server it connects automatically
to the readers and threads off a process to monitor card status.  Status
requests from the application ask this thread for status instead of the
reader.  Now you can run simultaneous GetStatusChange functions, transmits
and everything else you want.  I wrapped a mutex around all reader
functions so you can share transmit/status requests.  Also, I have fixed
Begin/End transaction so they will block until another application quits.
Since the libraries aren't loaded/unloaded as much the memory leaks are
almost none.

I should have a release out next week.  I will probably end up using this
one for good but I'm taking suggestions.


Dave
