ser2net + socat + gammu。 socat终止

I am developing small app that will send SMS using remote device as gateway.

These devices are connected with VPN, but it doesn't matter.

SMS gateway has physically serial port /dev/AMA0. I'm using ser2net on SMS Gateway to share serial port over Internet, and I'm using socat to create virtual serial port on VPS and "receive" shared port.

Here are my confings:

SMS Gw:

cat /etc/ser2net.conf 
3333:raw:0:/dev/ttyAMA0:9600,8DATABITS,NONE,1STOPBIT

VPS:

socat pty,link=/dev/tty_remote_serial,waitslave tcp:10.8.0.2:3333

我用来gammu控制短信设备。当我登录 VPS 并执行此命令时，我看到：

gammu identify
Device               : /dev/tty_remote_rpi_serial
Manufacturer         : SIMCOM_Ltd
Model                : unknown (SIMCOM_SIM800L)
Firmware             : Revision:1308B08SIM800L16
IMEI                 : 867XXXXXXXXXXX23
SIM IMSI             : XXXXXXXXXX491925

而且它是完美的。我可以使用远程串口，一切都很完美。问题是当我再跑gammu identify一次时。设备/dev/tty_remote_rpi_serial因终止而不存在socat。当我重新启动socat服务时，一切正常。我必须重新启动socat每个关闭的连接（来自 mincom）或执行的命令 ( gammu identify)。

有没有办法防止socat终止？

答案1

使用

while sleep 1; do
    socat pty,link=/dev/tty_remote_serial,waitslave tcp:10.8.0.2:3333;
done
