Quite frankly, the pty support was suggested and contributed by another user, and while it works on Linux, I haven't tested it on Mac, as I don't have access to MacOS X. Likely pty is handled a bit differently there, and you can troubleshoot the issue by checking if this https://github.com/saleyn/erlexec/blob/master/c_src/exec.cpp#L1134 function call is supposed to work on Mac.

Sorry for the misunderstanding, Erlang is running inside VirtualBox VM that runs Ubuntu, so it fails on Linux.
Thanks for getting back to me! I'll try to update this issue if I figure it out.

After some experiments, it turned out that the PTY mode works perfectly if the code doesn't attempt to disable ECHO mode.
In my case, I do not care about ECHO mode, so I'm not sure if it's correct to deny PTY mode completely in case if disabling ECHO fails. Certainly not in my case. Would it make sense to just ignore the failure to disable ECHO mode and continue setting up the PTY?
Thanks!

What is the OS error that you are getting when there's a failure to disable echo?

"Inappropriate ioctl for device"
from erlexec.
I think it should be safe to ignore the error. What the error means is that the standard input is not a terminal, and it can't echo there anyway. See:
http://unix.stackexchange.com/questions/82658/bash-script-error-stty-standard-input-inappropriate-ioctl-for-device
I'll commit the fix.
