When men were real men and typed their own AT commands... 這篇文章簡單的為您介紹了如何使用手動的方式，使用GSM。

Contents

需求

  • 安裝最新的u-boot boot-bootloader的GTA01Bv2 或 GTA01Bv3(透過USB)。
  • 不要連接任何debug board!

實際操作

啟動系統

  • 確認你所使用的 rootfs在 /etc/network/interfaces 下包括 'auto usb0'
  • 將主機的usb0介面設定為 192.168.0.200 netmask 255.255.255.0 See USB_Networking
  • ssh to root@192.168.0.201

停用 getty

我們預設的映像檔在/dev/ttySAC0都包含了getty，請編輯/etc/inittab ，並且停用該通訊埠的getty。

消除loglevel

NOTE: You don't need this in kernel builds with patchset ≥ 1288


為了避免kernel寫入 /dev/ttySAC0，你必須使用 dmesg -n1.

啟動GSM Modem

  • 檢核 getty 是否存在，或者是其它的程式是否在 /dev/ttySAC0 上執行 
root@fic-gta01:~$ lsof | grep ttySAC0
  • 若gsmd 目前使用 GSM modem，使用下列指令停用它： 
root@fic-gta01:~$ /etc/init.d/gsmd stop
  • 啟動GSM Modem 
root@fic-gta01:~$ echo "1" > /sys/bus/platform/devices/neo1973-pm-gsm.0/power_on

連接到GSM Modem (using socat)

  • If you have the command socat (built and installed): 
root@fic-gta01:~$ socat - file:/dev/ttySAC0,crtscts,crnl
AT-Command Interpreter ready

Connecting to GSM Modem (using cu)

If you don't have socat, you can use cu, although it has problems with file permissions and hardware flow control.

  • change permissions on ttySAC0 
root@fic-gta01:~$ chown uucp.uucp /dev/ttySAC0
  • setup /usr/spool/uucp 
root@fic-gta01:~$ mkdir -p /usr/spool/uucp
root@fic-gta01:~$ chown uucp.uucp /usr/spool/uucp
  • enable CTS/RTS flow control 
root@fic-gta01:~$ stty -F /dev/ttySAC0 crtscts
  • access the GSM Modem UART 
root@fic-gta01:~$ cu -l /dev/ttySAC0
Connected.
AT-Command Interpreter Ready
OK

If it hangs on "Connected" message then probably your device has a non-working GSM modem - check Bug #256, also you may want to try powering off the modem then on again as this worked for me

cu seems to have problems with the hardware flow control. The one way I always managed to get GSM working is to start cu first and then on a different console issue the stty command. --DanielWillmann 01:15, 20 March 2007 (CET)

Up the "Amp right" volume to hear the speaker on both ears, then dial (note the ; at the end of the dial string, this signifies a voice call, if you omit the ; it is regarded as a data call).

Using gsmd

You can use the gsmd and libgsmd-tool programs to have a slightly more high-level interface to the GSM Modem. It's still console based, though.

For further instructions, see gsmd

Using tui

Tui (available from sourceforge) is able to do all this. It is still text-based, but input-rxvt can take data from touchscreen, so you can actually do the calls using your finger. It also plays wav file on incoming call, so it is theoretically usable. It even does caller id.

When men were real men and typed their own AT commands...

Thankfully, this may now be partially obsolete. The dialer now works!

This is a short guide how to manually get GSM going.

Requirements

  • GTA01Bv2 or GTA01Bv3 with very recent u-boot bootloader, providing usbtty (serial over USB) support)
  • Do not connect any debug board!

Walk-Through

Booting the system

  • Make sure the rootfs you use has 'auto usb0' in /etc/network/interfaces
  • Configure the host's usb0 interface to 192.168.0.200 netmask 255.255.255.0 See USB_Networking
  • ssh to root@192.168.0.201

Disabling the getty

Our default images all have a getty running on /dev/ttySAC0, please edit /etc/inittab and disable the getty on that port

Reducing the loglevel

NOTE: You don't need this in kernel builds with patchset ≥ 1288


To keep the kernel from writing to /dev/ttySAC0, you need to use dmesg -n1.

Powering up the GSM Modem

  • verify there is no getty or any other app running on /dev/ttySAC0 
root@fic-gta01:~$ lsof | grep ttySAC0
  • If gsmd is using the GSM modem, shut it down with 
root@fic-gta01:~$ /etc/init.d/gsmd stop
  • power-up the GSM Modem 
root@fic-gta01:~$ echo "1" > /sys/bus/platform/devices/neo1973-pm-gsm.0/power_on

Connecting to GSM Modem (using socat)

  • If you have the command socat (built and installed): 
root@fic-gta01:~$ socat - file:/dev/ttySAC0,crtscts,crnl
AT-Command Interpreter ready
