Is there a way to temporarily unload or put on hold, the main application?
Essentially block that application from the packet driver, and start
up some other application such as an email package, then enable the
main application again?  Possibly an alternate packet driver interrupt
vector that when in use, would cause the primary vector to be on hold?
