Hi. Can anyone tell me how to read and write to the serial port using OPL? I've got a Psion 5 manual but I'm not sure that they work the same way as the 9210. Any help would be appreciated. I've an idea for a prog. If I can get it to work I will share it 
Access to serial port in OPL
I guess from all the replies that either no-one is interested in OPL or the current alpha/beta version does not support the serial port
Hang on! I'm interested in OPL at the moment but my time is being taken by something else (you'll find out soon ).
If I remember correctly (though I can't remember ever getting this to work), the serial port is opened in the same way as you'd open a file.
At the moment, that's all I can offer you but there should be no harm in looking up old Psion sites for advice in this area (try 3-Lib, that was to the Psion what AllAboutER6 is to Symbian today!).
I'll post the address if I can find it, but if you do a search on 3-Lib, you should find something.
Thanx for the reply. Your right, the psion sites are the places to look and have already helped a lot. I now can write to the serial port, but not yet read. OPL v6 uses 16 bit strings and has left me a bit confused. I wont give up yet
