You can send info from the 41 to the 48. HP itself provided such tools both on their site and with the emulator card. I am not sure where to get the software from these days but if I remember correctly it is called inprnt (or something like that) and it takes printer output from just about any HP calc i/r device capable of printing and translates it into a text string. This works with the 41, 41 and 27 calcs. Probably others -- I can't recall having tried with a 28 but I would be quite confident that it would work.
There is no way to take input however since the i/r module has a transmitter only and no receiver.
