VSP Manager
From DDUtilV3
VSP Manager is a software program that creates serial port pairs. It DOES NOT allow port splitting which is defined as allowing multiple programs to connect to one source. If you need port splitting try VSPE.
If you are an Amateur Radio Operator and would like to use VSP Manager for your *Personal* use, contact me with your call letters and I'll be happy to send you a copy.
Please Note! If you're not a licensed Amateur Radio Operator don't bother to apply. There are no exceptions to this rule.
