8. Interaction with Emulator
Console on 5554 adb on 5555
>telnet localhost 5554 1. redirect host port(5555 or 5557
or ...) to guest(10.0.2.15:5555)
1. Commands slirp_redir()
event 2. ping to adb server
geo, gsm, sms emulator: sent '0012host:emulator:5555'
to ADB server
network, power 2. adb_connect(“shell:ls”)
