Com Port for PsiWin

Likes # 0

I have just found a thread from 2009 by tallboy about requiring a com port for his Psion connection. It's nice to know someone else is still using a trusty Psion! I am about to have a similar problem as I am building a new PC. I also encountered problems with a com-usb converter when I tried to use one with my Vista laptop. If you spot this thread tallboy - did you get yours sorted? I guess I could install a card with a com port, does anyone know of such a card?

I used to be a Psion enthusiast and my Psion-based website is still in place, although it hasn't been updated for a number of years now. PsiWin connections were always somewhat temperamental and they frequently didn't work with USB/Serial adapter cables. If you want to use a Serial COM port, I'd strongly recommend installing a PCI Serial Port card to implement the port properly. The question that I don't know the answer to is whether PsiWin 2.3.3 will actually run in Windows 7, if that's the operating system you're going to be installing.

You don't mention which model of Psion you have but, with a Series 5 and 5mx, I never actually connected them with PsiWin. Instead, any files I wanted to transfer to the PC I put on the Compact Flash card and then plugged that into a CF reader in the PC. My internal drive was copied to a folder in the CF card so that the entire Psion was backed up in the PC.

I wrote some simple Psion Basic programs, years ago, to control Industrial Machines for maintenance.

I used Serial (hand-built cables) since I didn't have a standard RS232 to connect to.

I seem to remember I could do almost everything I wanted by sending ASCII codes. (Printing to the port??)

So I could start a motor by sending "Mxx1" and Stop by sending "Mxx0". xx being the number of my motor. All highly specific to my situation.

The only thing that defeated me (Series 3 thru' 5) was I wanted a motor to start when I held down a key and stop when I released it.

I had all the tech manuals and Googled (or Alta Vista'ed??) and even spoke to Psion Tech Support.

Key Press and release detection wasn't possible. I worked around it in the end.

Fun days.

I'm using a Series 3c. It may be old but it's still in almost daily use. I like the reliability, the simplicity and the security (no-one is ever going to hack it!). I have manage to run PsiWin on Win3.1 95, 98, XP and Vista. I'm not sure about Win7 but I'm hoping that XP mode will help if necessary. mgmcc, when you mention Compact Flash, are you talknig about the Psion cards? I didn't know there there were readers for these cards, this could be an option. Also the com port card you show seems cheap enough. Thanks for the info.

The Series 5 onwards used standard Compact Flash cards as used in early digital cameras and these could be read with a CF card reader. The SSDs used in the Series 3 devices are a proprietary format for which there wasn't, to my knowledge, a reader for the PC.

Oh yes, I remember now when Psion switched to more standard components. I never upgraded to the Series 5 as the software I was using on the 3 was not compatible. Still, as I say the old Series 3 is doing sterling service. I have had to rebuild it a few times though with parts scrounged from other machines. The problem is always a weakness with the hinges. Never a problem with the software though.
