Barrow" Subject: Re: PowerBook G3 internal modem To: Patrick Callahan , linuxppc-dev MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Sender: owner-linuxppc-dev@lists.linuxppc.org List-Id: I have problems ( more than likely different ) too with my modem too on a desktop G3 with the 2.2 kernel, & on an older 6100 with a version of linuxppc from last year when I went serial debugging the line I noticed bit errors for particular combinations of characters. On my G3 to get the modem to work reliably I have to start the Mac OS first then warm boot into linuxppc. I believe this causes some registers in the scc serial chip to be initialialised by the MAC OS which aren't being initialised by the linuxppc driver. --- Patrick Callahan wrote: > > There's some problem I have that prevents kppp from > working correctly when I > start it from a terminal window of a user account. > When started this way it > freezes after receiving just a few packets.
