At the moment, I cannot figure a way of running this precompiled "conv.exe" using commandline arguments.
Thus, I need Python to call the program, wait until it loads up, then enter a known sequence of characters so that the function will run. The program conv.exe I call looks like this. -------------------------- Welcome to conv.exe This program was written by .... Please select from the following options: h- (help) r- (read) ...etc Enter your request: --------------------------------- I need Python to start the program, wait a second and then issue a few characters to the program. Hope this makes more sense!
