Yeah, great. As currently I am the only person who works activly on a free implementation of the binary protocol used for the msm modem in the Palm Pre I need help :) Currently I am at work so I cannot tell you everything about what we have done so far, just a short overview. More details when I am back home. Currently most research results are on the Modem Research Page in the webos-internals wiki (http://webos-internals.org). Only informations I figured out about the payload data are missing. But I will update them in the next time. So we currently have discovered most details about the Layer 1 of the protocol and a first implemenation is nearly finished in the msmcommd daemon (at http://git.freesmartphone.org/?p=msmcomm.git;a=summary). Future work is dedicated to the payload data. It should be very easy, cause the basic structure is already known (more details later). The biggest problem with the modem protocol in general is, that the protocol is autogenerated by some properitary tools from qualcom. So the byte sequences can change from one release of webOS to another. > Our resident msmcomm expert here is Simon 'Morphis' Busch, who is > hopefully subscribed to this mailing list as well.

If you want to some more details quickly just contact me over jabber (morp...@jabber.ccc.de). Even welcome from me, and I hope we get used to this bastard modem as quickly as possible :D cheers, morphis _______________________________________________ Smartphones-userland mailing list Smartphones-userland@linuxtogo.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/smartphones-userland
