[android-porting] How to make my libreference-ril.so work in the HTC dream unlock developer phone?

[Bo]

Dear Sir:

I want to make my RIL implementation (hardware/ril) work in the HTC
dream unlock developer phone. I want the HTC dream android to use my /
system/lib/libreference-ril.so instead of libhtc_ril.so

From the posts of this group, I know it should work on android
emulator by
manually /system/bin/rild -l /system/lib/libreference-ril.so -- -d /
dev/ttyS0
or do it in init.rc
service ril-daemon /system/bin/rild -l /system/lib/libreference-ril.so
-- -d
/dev/ttyS0
or the configure the rild.libpath and rild.libargs in the /out/target/
product/dream-open/system/build.prop
however, in the original file build.prop, it only indicate the
rild.libpath=/system/lib/libhtc_ril.so, but does not indicate the
parameter rild.libargs

The problem is that in the /dev/ of HTC phone, I can not find ttyS0. I
tried to use tty, ttyHS0, ttyMSM0 and ppp in folder /dev/ of HTC
phone. It always reported RADIO_UNAVAILABLE in radio trace below.

The code of main function of /hardware/ril/rild shows that the
RIL_RadioFunctions of libhtc_ril.so got the tty device, but I do not
have the code of libhtc_ril.so. So I do not which tty device HTC phone
uses.

I guess I selected wrong the serial device. Could anyone tell how to
make my libreference-ril.so work on HTC phone instead of its
libhtc_ril.so?

Hi
I have the same problem with Bo
There is codes in reference-ril.c
if ( fd >= 0 && !memcmp( s_device_path, "/dev/ttyS",
9 ) ) {<<<<maybe ttyS should be changed to ttyHS or ...
/* disable echo on serial ports */
struct termios ios;
tcgetattr( fd, &ios );
ios.c_lflag = 0; /* disable ECHO, ICANON, etc...
*/
tcsetattr( fd, TCSANOW, &ios );
}
in fact,I have changed '"ttyS" ,9' to'"ttyUSB,11"'(ttyUSB is my
device file ) ,but it still not work
Could anyone tell me how to do?
Thanks
