Nov 04 06:51:44 <trashead> Anyone here???
Nov 04 08:52:56 <trashead> Anyone there! Need some help in understanding the ofono code..
Nov 04 08:55:08 <trashead> ??????????
Nov 04 08:57:21 <holtmann> trashead: In what area?
Nov 04 08:58:17 <trashead> ofono..
Nov 04 08:58:26 <trashead> gatchat
Nov 04 08:58:52 <trashead> In slide 10 of the presentation available 
Nov 04 08:58:57 <holtmann> What is wrong with that. That piece is perfect.
Nov 04 08:59:04 <holtmann> Which presentation?
Nov 04 08:59:10 <trashead> Japan.. 
Nov 04 08:59:25 <trashead> I'm new to the ofono and trying to understand the code..
Nov 04 09:00:25 <holtmann> You know that we have 140000 lines of code right now.
Nov 04 09:00:28 <trashead> GAtChat uses GAtIO directly? 
Nov 04 09:00:58 <trashead> OR it should use through ATMux or HDLC?
Nov 04 09:01:12 <holtmann> Depends on your hardware.
Nov 04 09:01:26 <trashead> Please elaborate!
Nov 04 09:01:31 <holtmann> GAtHDLC uses GAtIO. And so does GAtChat.
Nov 04 09:01:42 <holtmann> GAtMux uses GAtHDLC.
Nov 04 09:01:54 <holtmann> And GAtPPP also uses GAtHDLC.
Nov 04 09:02:13 <holtmann> GAtIO is a an IO abstraction layer on top of GIOChannel.
Nov 04 09:02:27 <holtmann> It allows us to suspend on protocol and then run another.
Nov 04 09:02:27 <trashead> Ok!
Nov 04 09:02:39 <holtmann> For example when you switch from AT commands to HDLC framing with PPP inside.
Nov 04 09:03:34 <trashead> In what scenario's we'll be shifting from AT to HDLC...?
Nov 04 09:03:52 <trashead> Also can you give acronym of each...
Nov 04 09:04:07 <trashead> Sorry if my questions sound silly to you...
Nov 04 09:04:12 <holtmann> Seriously. That is what Wikipedia and Google is for.
Nov 04 09:04:38 <trashead> :-) 
Nov 04 09:05:00 <holtmann> AT commands are just AT commands. Check 3GPP 27.007 standard. And it predecessors. Most likely some ITU stuff.
Nov 04 09:05:23 <holtmann> HDLC is an RFC.
Nov 04 09:05:30 <holtmann> PPP is point-to-point protocol.
Nov 04 09:05:41 <holtmann> MUX is 3GPP 27.010 standard.
Nov 04 09:06:25 <trashead> Thanks... 
Nov 04 09:06:26 <holtmann> PPP should be also an RFC btw. Just search for it. I don't remember the numbers.
Nov 04 09:06:45 <trashead> Ok that's fine..
Nov 04 09:07:34 <trashead> In what scenario's we'll be using MUX?
Nov 04 09:08:04 <trashead> And How many channels are supported?
Nov 04 09:08:28 <trashead> Is it one channel per Atom?
Nov 04 09:16:48 <balrog-k1n> no, atoms don't know about HDLCs
Nov 04 09:17:34 <trashead> Ok
Nov 04 09:17:44 <trashead> Then what is the purpose of MUX?
Nov 04 09:17:57 <holtmann> Multiplexing of TTYs.
Nov 04 09:18:02 <holtmann> Read 3GPP 27.010.
Nov 04 09:18:07 <holtmann> You really need to read that.
Nov 04 09:18:24 <holtmann> And only a few modems do use that. Calypso and IFX for example.
Nov 04 09:18:30 <holtmann> Others don't.
Nov 04 09:18:45 <trashead> ok!
Nov 04 09:19:04 <holtmann> Channel (or to be precise DLC) limit of the 3GPP 27.010 is 63 btw.
Nov 04 17:54:01 <denkenz> yang_office: Can you please take care of the Support Local Information task before the Cancel task?
