Asking for a friend ...

Phil_aka_Pip

... well, Nick actually, he's the bloke writing Java across the desk from me. Apparently there's this function in librxtx called CommPortIdentifier.getPortIdentifiers, he uses it to find what serial ports are available. I'm told it works on Windows, but when his product is run in a Linux environment it only reports /dev/ttyUSBn where n = 0,1,2,3. There are definitely others which you can see if you ls -l /dev/tty* (includes /dev/ttymxc4, /dev/ttymxc5). The existence of these others is crucial as the latter are the RS485 ports which he needs to tell me about so that my end of the software can use them. Does anyone know how getPortIdentifiers works, or what documentation might exist which would help us in getting this function to recognise those other ports?

Any help?

@Fretwired yes, there are several like it but that is quite a good one. we have also established that when I did the apt-get install on librxtx (or whatever they call it) I did do it correctly the bit about System.setproperty strikes me as being highly relevant since it tells getPortIdentifiers what things it ought to be looking for - in our case /dev/ttymxc* as well as other things.

fanx!

You mean any port in a storm?

Sesh

Have you tried turning it off and on again?

Yeah right, asking for a friend, nudge nudge wink wink

In the end we abandoned the idea of sniffing round the comms ports as that System.setproperty call tells it explicity what to look for (you can't just give it a base string or even say look for ttymxc*), which defeats the objective: if you have to tell it explicitly then you already know!

Did you honestly expect to find an answer to this on a guitar forum? Especially when you have access to the entire Internet and other dedicated forums....

I found lots and lots of references to this problem with google, and knowing that there are several Java writers on this forum theres no harm in asking if anyone has found anything useful

This place is awash with programmers, to be fair.  A lot of internet forums are.

Oooh look.  Crisps.  I'm going to eat those now.
