> def dataPort( self ):I was curious about the need for the sleep statement since I expected the exception handling to be enough since it triggers a retry after 2 seconds. But removing it, ogsmd retries allocating the missing channel in vain: if it doesn't work the first time, it won't work the others. Here is the failure pattern which occurs forever: * Exception: org.freesmartphone.GSM.MUX.NoChannel: Modem does not provide this channel * could not open channel CALL, retrying in 2 seconds I've tried: * setting a sleep between _ModemOn() and the first channel opening, to check whether the muxer need some more time to initialize => no luck; * changing the channels order so that 'ogsmd.call' be opened first => third channel opening fails whatever their order is. Seems that the place you put the sleep statement at is the only one right: the muxer just can't cope opening these 3 channels without waiting a bit between them. So, please, developers, apply the Jose's patch :) BTW, I've a - maybe naive - question: shouldn't the _ModemOn and _ModemOff low level methods be implemented into libgsm0710mux? Thanks, _g.
