我有一部已植根的 xperia Z 手机。我想发送 USSD 命令并得到答案。
我的第一个想法是通过 adb shell 接口通过良好的接口发送 AT 命令。
我列出了所有接口：
/dev/tty /dev/tty 5 0 system:/dev/tty
/dev/console /dev/console 5 1 system:console
/dev/ptmx /dev/ptmx 5 2 system
/dev/vc/0 /dev/vc/0 4 0 system:vtmaster
rfcomm /dev/rfcomm 216 0-255 serial
usbserial /dev/ttyUSB 188 0-253 serial
msm_serial_hsl /dev/ttyHSL 244 0-3 serial
msm_serial_hs /dev/ttyHS 245 0-255 serial
pty_slave /dev/pts 136 0-1048575 pty:slave
pty_master /dev/ptm 128 0-1048575 pty:master
smd_tty_driver /dev/smd 251 0-36 serial
unknown /dev/tty 4 1-63 console
我找不到好的界面。我试过这个命令集：
root@android:/tmp/tst # tail -f /dev/ttyHSL1 &
root@android:/tmp/tst # echo -e "AT\r" > /dev/ttyHSL1
但我没有得到答案。
知道如何找到好的端口吗？
EDIT1：根据 Alex P 的要求。

我没有安装 /dev/smd0 接口
