Qt embedded console commands request and reply

[bluscape]

I'm using Qt embedded on linux.
From the console (serial console) I use the following command to get status on my ppp:

/etc/rc.d/S09pppd status

The ppp will reply with "pppd running" or "pppd not running"

I would like to execute this request from my Qt application and read the reply from my Qt application.

How can I do this?

So I execute the command with a QProcess for example:

@QProcess qpCommand;

qpCommand.execute("/etc/rc.d/S09pppd status");@

which is creating the desired effect.

Now how do I read the response?

@qpCommand.readData(char * data, qint64 maxlen)@

[bluscape]

But readData is a protected function?

QProcess::execute() is a static method. It does not return any output of the started command/executable. You will have to use the non-static methods in order to ready any data.

@
QProcess p;
p.start("/etc/rc.d/S09pppd status");
p.waitForFinished(); // blocks!
QByteArray output = p.readAllStandardOutput();
