	I have run into what appears to be a DOS 2.x bug (MS DOS 2.11,
	PC DOS 2.10), and I'm wondering if anyone else has seen this
	or knows of more details.  Especially if you have implemented
	a networking node, I imagine you have run into this....

	We have an installable character device driver.  After we have
	read from or written to it for approximately 33 MB, it appears
	that DOS closes the file handle to the driver.  IOCTL's to the
	device continue to operate correctly, but read's & write's 
	fail until the driver has been re-opened.  We have never seen
	similar behavior on MS DOS 3.10.

	Please respond by email.  THANKS!
