Could you please elaborate on what you mean by "serial port service" and how does one check for its existence ?
I bought a 7610 in Nov04. This is the first symbian device i am working with. Which symbian device do you know that definitely supports the "serial port service" ?
basically I think it is BT service profile (or something), anyway my 3Com BT connection manager shows them in a list when I check service profiles for any available phone.
Anyway, I basically only tried the Borland target debugging with 3660 & 7610 and only got it working on 3660. Haven't got too much use for it lately, so haven't really needed to check any other phones.
