//	DLL to provide interface to allow G8BPQ switch to use UZ7HOPE as a Port Driver 
//
//	Uses BPQ EXTERNAL interface
//

// Interlock and scanning with UZ7HO driver.

// A UZ7HO port can be used in much the same way as any other HF port, so that it only allows one connect at
// a time and takes part in Interlock and Scan Control proessing. But it can also be used as a multisession
// driver so it does need special treatment.
