Warning: NewB here
I have just migrated from PCLOS Gnome 2008 to OpenSUSE v11 - it’s great, allowing much greater functionality and ease of use, especially updating. 
I would also like to get connectivity with my aged Psion 5 PDA. I have downloaded KPsion using YaST2 and it appears to run pefectly, save that of connecting to the Psion. I have noted that the Psion is looking to connect via cable at various data rates, so I have chosen a mid range 57600 baud rate.
I have set KPsion to attempt to connect using /dev/tty/USB0, which I understand it to be the default USB setting, using 57600 baud rate.
I have checked the system overview and seen that the Keyspan USA-19HS USB-to-Serial connector is configured correctly and recognised by OpenSUSE. I have also used this extensively with Windows XP and had many occasions to backup said Psion - I just want to dump Windows if at all possible.
Has anyone got any clues what I can do to allow the Psion 5 to be seen by the computer using KPsion. I have seen a note on the www about allowing TCP 7501 in the firewall, is that a good idea?
Cheers for any help.
