console app question

[galil]

Situation is, I want to include a console progie to my installer (nsis is the best ), however it has one anoying (in my case) feature - to quit it you have to press enter-key (i guess it was implemented to let a user see output or something). This proggie works several times during install, and each time user would have to click enter - and that's pointless and irritating.
Is there some way around this, like emulating a key-press? Terminating a dosbox is not an option, I tried it and it messed up the proggie's work.

PS: I realise that my question is not quite related to NSIS, but I didn't know where else I could ask, and I see lots of experienced people here, programmers and such...
