RS232 with 49G+ and/or 50G
This problem is driving me crazy. I own a 49G+, and would storm out of here and shoot someone for a 50G if it would only communicate with a GPS receiver and/or Kenwood "data radio" via RS232. Here's what I know: The advertised RS-232 capability isn't fully realized. The voltage levels aren't "true" RS-232. Th... 1 Nov 2006 17:50

I've been lurking here a while, but not posting. I read a sort of funny post dated last March begging the new CEO to revive the ailing calculator division. Six months later, can anyone here (Jean-Yves, cyrille, etc) say whether or not there has been a change in the way HP approaches the calculator division, and t... 12 Oct 2006 01:50
