Gracefully terminate Run Program()

Question

I am in a situation where I use Run Program() to send files to an FTP/MTP site. By and large everything works great, but sometimes there's a kink in the connection and the program lags indefinitely. I have recreated this problem from the command line and it's basically a lost connection type event. But I need to Ctrl-break out of CMD to stop it.

In JMP I want to put in a timeout to reduce the risks, however I haven't been able to get one to work well. Currently I build the timeout into the While(!(x << isReadEof), Wait(0.1)) command such that x is set to 0, breaking the Run Program. But when I do this JMP will often freeze for a short or longer time to fix (or while something else is fixed) background stuff that had been going on.

Is there a way to force close Run Program() as well as the process it invoked w/o risk to freezing JMP?

Thanks!

Thanks for the idea @Craige_Hales! I had tried the <<write "bye" before, but without the <<writeEoF ... so perhaps that would make a difference. I had thought of other FTP clients, but this script would be used across a larger user base on which I can't control the FTP client piece.

If I find a solid thing that works, I'll post it here, but I'll def try some of your ideas!
