| Hi Jeff, yes we solved the mystery. It was actually related to the implementation of the serial communication, that is, the waiting time to the ack to come was too short, and it seems somewhere in the javax.comm times are strangely measured depending on computer speed. We still don't know exactly what is going on there but increasing the communication timeout helped. That is no good answer but at least it is not related to Equinox.
Thanks for all help!

Peter,
did you ever resolve this issue?

Hi,
we are trying to communicate via the javax.comm interface with serial ports on windows. The strange thing is, everything works fine outside OSGi (Equinox). Exactly the same javax.comm.jar dropped into the Equinox root classloader or into a bundle does give us errors in the serial communication, essentially acks not coming in time so we have to resend them.
However, when we load the machine, e.g. have the Windows mediaplayer on without even music (!) everything works fine.
We are really out in the dark here. Has anyone had similar problems and sohuld we try other serial comm implementations and which?
Thanks for hints on this!
