I am constantly amazed at what the 48SX can do, especially how one wants to use it to dial telephone ... but has anyone thought about using the infra red to control your VCR, TC, stereo ..... Ben

I wonder, though, since the calculators have to be 2 inches or less apart (according to the manual, p 620) to do the infrared transfers, would the transmitter be strong enough to talk to the TV, say 15 feet away?? Even if you could get it to generate the correct type of signals for the TV, VCR, etc, you might have to hold it within 2 inches of the receiver of the device. :-( It's a great idea, though--maybe it really could work--Any comments from the HP side of the fence??

The printer doesn't have to be two inches away. The TV etc. may not pick it up over 15 ft., but certainly more than two inches. I am VERY interested in the possibility of recording and transmitting IR remote signals. It just HAS to be possible!!!!!! -Ken ------------------------------------------------------------------------------- | _ , __ _ _ | "It's green . . ." | | ' ) / / ) // // | Mr. Scott | | /-< _ ____ /--< __ . . ____ _ // // | | | / ) </_/ / <_ /___/_/ (_(_/_/ / <_</_</_</_ | Loooove that .sig | | <khbsnsr@jupiter.nmt.edu> | | ===============================================================================

(Maybe this should be added to the list of answers of frequently asked questions?) Somebody did write an HP-28 program for controlling common household equipment via infrared signals. No, it does not require that the calculator be two inches from the device. Apparently the receivers on most VCRs, televisions, et cetera are significantly more sensitive than the calculator receiver; mine worked from 10 feet away. -- edp

You may hear something else from the Corvallis guys, but in case you don't: The IR transmitter has an actual range of several feet. Varies from machine to machine, but in an earlier discussion on c.s.h some users reported printing stuff at 8 and 10 feet. The transmitter's not the problem. HP intentionally hobbled the receiver, allegedly at the request of a university prof who allegedly beta-tested the machine and discovered the potential for classroom cheating during tests (e.g. "Hey Joe, what's the answer to 3(b)?" XMIT BUFLEN SRECV). Allegedly. Regards Ray Depew IC's by Bill and Dave rrd@hpfitst1.hp.com I just use 'em, same as you guys. Allegedly.

And the 48 should have a distinct advantage in the fact that it has an IR receiver. This should make it capable of "learning" your remotes on the fly like a "universal remote" does.
