[Gta04-owner] Modem logs

[Denis 'GNUtoo' Carikli]

Hi,

I found a way to get the modem logs:

Open an ssh shell and do:
serial_forward -n /dev/ttyHS_Diagnostic -p 8022 -t raw

hg clone https://code.google.com/p/qcombbdbg/

Apply that patch:
$ hg diff

cd scripts/tools/
./show_msm_messages.rb telnet

And you'll see the modem logs...

It may help in debugging modem issues.

PS: SHR lacks ruby so that's why I used telnet...
