There is some incompatibility in protocols:
- The HP 48 natively supports bidirectional SIR (serial over Infra Red), not IrDA.
- The HP 48 can be tricked to read RedEye using software (normally used to receive ROM dumps).
- The HP 50 natively supports bidirectional IrDA, not SIR.
- The HP 50 can print RedEye, but not read it.
Therefore it should be possible to print something from the HP 50 using the RedEye protocol (CF -34) and to receive it on the HP 48 using the special RedEye receiver software.
If one would write an IrDA input/output program for the HP 48 one could use that, but I am not aware of such a thing.

Thanks for answering. I was kinda hoping to transfer some files without urchasing serial cable for the 48 but i gues theres no way around it since theres apparently no native support for transfer between the two calculators..
