But when you got the error: Not all params are supported by kernel
You was using rxtx and changed to javacomm? Because that can explain the problem that I experienced in Linux/ppc. If not, you are a lucky man :). Anyway, what modem / phone model are you using?. Can it to be used to get calls too?. Model appear in the compatibility list? If the phone model does not appear, I suggest you put it and say that the phone has a specific 115200 baud rate. This can help some other people. Pietro On Jan 14, 12:36 am, crimson <[email protected]> wrote: > Hi Pietro, > > Thanks for the suggestion.
