Psion Infra-Red

Many Psion SIBO and all EPOC PDAs have built-in infra-red ports. The most common uses of these included file transfer with other Psions, and printing and networking using dedicated Psion accessories such as the Psion Travel Modem and Psion Infra-Red Link.

Less well known is that all Psion models could make use of the infra-red ports as an alternative to the serial port for PC connection using Psion Connect and, later, PsiWin.

Given how hard it is to get hold of the Psion RS232 Link Cable today, this makes infra-red an appealing mechanism for synchronizing your Psion PDA.

Configuring this is somewhat troublesome however – especially in 2015 – so this post records the appoach I took and hopefully can serve as a guide for anyone else crazy enough to try it.

The Hardware

My set up involves the following devices:

  • Psion Series 3mx – you can still find these on eBay
  • Alcom IrDA USB
  • Windows 98 – running in VMWare Fusion 9 on OS X Yosemite

The Software

It’s easy to forget – with the relative maturity
