The 48 could communicate with IR on some computers, and not on others. The newer 39g+ should work as it uses IrDa. Personally I have not tried it though, so that is just what my brain remembers hearing. . . TW

Re: hp39g infrared transfer with computer Message #4 Posted by Ron Ross on 15 July 2004, 2:01 p.m., in response to message #3 by g Then you are out of luck as you do not have the HP39G+ (which might not work either, but the old 39G definitely won't). This is because the IR is transmited via its own protocol which is based upon the IR printer these calculators could use. This IR protocol was then modified to transmit between the calculators themselves with the 38/48G series. The 39G merely adopted this protocol from the Hp38G. You might be able to pick up the IR signals but you will have to write a PC program to decode. Additional information can be obtained from www.hpcalc.org for the Hp38/39G family of calculators even though it is a 48/49G based site.
