Shell with several arguments including "<"

Hello,
I'm trying to launch with B4PPC a DoS command but it doesn't work.
Normally, I should type ptts.exe < texte.txt
With B4PPC, I tried shell ("ptts.exe", "< texte.txt") but it does'nt work and the DOS window is so fast that I cannot see any error message.
Can someone help me ?
Thank you.

emm... you must open CMD first. you can do it in "Run" dialog.Input "CMD"
and now you can see what error you have

Good idea, but I don't know how to do it in "Run" dialog.Input "CMD".
Could you give me more details please.
Thank you.

You can create a batch file and run it.
It is also possible to do it all from code with the help of the Door library.
Note that the redirection will only work on the device.
