We are trying to run a process that reads info from the serial port and places
it in shared memory that will then be accessable to a performer application
program based on perfly. The process that is polling the serial port runs fine
until perfly starts a pfFrame. The serial read process then hangs...seems to go
to sleep but doesn't die. We don't understand why this is happening...the
performer application runs merrily along but the ability of the other process
to feed performer data is gone. We are using the standard shmget and shmat
stuff for our process.

Thanks for the help! Larry
