[Sdio-linux-devel] Using cat pharos GPS data

[boku <bok...@gm...>]

Hi,
    I use cat /dev/ttyxx to check if there's data from pharos GPS. It did
output some text data such
$GP.... 0,50.0,50.0*05
But why the "cat" doesn't quit?  It just hanged there unless I type "Ctrl+C"
to quit.
Is it correct?

<ps> I checked some message and found while upper application uses
gps_start_tx() and it did use CMD 52 to write pharos UART IER register.
After that, it is hanged.

BR,
Victor
