Can you use gnome- > terminal or xterm to do that? Run picocom in your xterm of choice for this. Picocom handles the serial comms and the xterm interprets the ANSI escape sequences. There is even an easy mechanism to envoke the file transfer program of your choise. Several small programs working well together, true Unix. Just spent the day configuring expect in front of such a combination, so we can now, connect to a unit, work out what baudrate it's running, at, upload three separate software files, check the hardware type and perform a different configuartion sequence for each. Automating 20 minutes of previously tedious production work. Avoid minicom, it tries to do it all, and hence does none of it well. -- Bob Dunlop -- Next meeting: Bournemouth, Tuesday 2011-11-01 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ How to Report Bugs Effectively: http://goo.gl/4Xue

I was going to ask if that's what he was doing but thought better of it. :-) > Can you use gnome- terminal or xterm to do that? No. There's minicom(1), though it's a clone of a DOS program, seyon(1), which uses an xterm is the ANSI-handling terminal, or cu(1), which as `call Unix' is really part of UUCP but is in its own package these days because it's handy even without the rest of UUCP. Again, it just runs at the command line so that will handle the ANSI. There are others, like cutecom, but I don't know about ANSI support for those.

Kind of like a platform-agnostic C header file with knobs on. ftp://ftp.samba.org/pub/unpacked/samba_4_0_test/librpc/idl/preg.idl I suspect it's something like Microsoft's DCOM that adds the introspection stuff.

Re: [Dorset] OT(ish): IDL
Ralph, Since yesterday, I've followed up on the links you provided and had 'long and meanigful' discussions with the guys who maintain the Standard. As a result, I'm a bit more clued up than I was yesterday evening.

I suspect that you're right. My boss Chris has always maintained that (for all their faults) MS do produce very functional development tools.

Purely from the Docs? Yep. The fine man pages traditionally. Supplemented by books, other source code that uses them, and the function call source itself. I wouldn't expect an IDL to be able to describe all the semantics of an interface so even if some whizzy MS GUI lets you inspect it and see what you can poke, you may only be playing all the right notes but not necessarily in the right order.

The interface description for your D-Bus object is written in XML: http://dbus.freedesktop.org/doc/dbus-specification.html#introspection-format and is available at runtime using the special org.freedesktop.DBus.Introspectable interface on the object.
