(I am having no luck in selecting my serial port from a java application).

I think this is a bit relevant to the long running thread on "other matters". Unfortunately I can get no answer on this question, I have tried the ubuntu group, to no avail. I had the thing working with Red Hat and with Debian. Perhaps part of the problem is that Java has been upgraded. Perhaps some one could tell me which USB to Serial I should purchase for the lappy (My Keyspan is unsupported by ubuntu and I have searched for a chipless one (as suggested) to no avail (I also can not understand how one would work (as it must have an address)but I am no expert)). If they could also tell me what to download I could bring it all along to the next meeting. As an aside both rxtx stuff and sun java are in the repositories. Indeed I got as far as getting a message telling me I should be in group uupc, that was it. (The computer then died (I was in hack mode) allowing me no access as root! Luckily it was the play partition of my back up computer.) In the mean time I will have to use windows, which is a pity as it is on show to other club members and will be on show to the public in August at the Plymouth show.
