Is my understanding correct for rild?

[June Ree]

Hello,

I have RILD questions.

1. I see a phone initialized like this..
rild.libpath=/system/lib/libxxxx.so
rild.libargs=-d /dev/smd0

So it means, it communicates with /dev/smd0, doesn't it?
So it means, I can interact with /dev/smd0 for modem operation, can't i?

2. I see a phone initialized like this..
rild.libpath=/system/lib/libxxxx.so
rild.libargs=-d /dev/ttyS0

However, in this case, this phone doesn't have /dev/ttyS0 file..then how the rild can communicate with /dev/ttyS0, which doesn't exist in the phone?

Thanks,
