Old Macs used to have a +5v power pin on the serial ports. Alas, newer ones dont, and I want to connect summat to the serial port which needs a 5v power supply at, say 20mA. It has been suggested to me that I can just connect to the Handshake out Pin, and use that for my +5v. This sounds too good to be true yet I suspect some such trick must work. Anyone out there like to comment on this? Thanks, Ralph
