Anyone ever fooled with one of these things? I just built a new PC for a Dr. and because of some special heart monitoring systems that are hooked into it he has no free COM ports. Get this...the system has the normal 2 COM ports that all PC's have plus 2 more that are on a special card that the heart monitoring machine & software use. My problem is that all 4 ports are connected to various cables that the monitoring machine uses thus there are no free ones. Not normally a problem but the Doc decided he wanted a modem on the PC as well. I'm thinking USB might be the way to go but have never messed with one. Any thoughts???
