IR transfer between hp48 and hp50

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.
