I use:
<file name="/usr/local/bin/cmd'>
#!/usr/bin/env bash
# Copyright (C) 2018, cygSimple
#   mailto:cygSimple@users.sourceforge.net
#   https://sourceforge.net/p/cygsimple
# File: cmd

`cygpath "$COMSPEC"` "$@"
</file>

and

<file name="/usr/local/bin/start">
#!/usr/bin/env bash
# Copyright (C) 2018, cygSimple
#   mailto:cygSimple@users.sourceforge.net
#   https://sourceforge.net/p/cygsimple
# File: start

cmd /c start `cygpath -w -- "${@//&/^&}"`
</file>

The file /usr/local/bin/start uses the file /usr/local/bin/cmd because 
of PATH.

I use another such file to start the Windows version of gvim.

<file name="/usr/local/bin/gvim">
#!/usr/bin/env bash
# Copyright (C) 2018, cygSimple
#   mailto:cygSimple@users.sourceforge.net
#   https://sourceforge.net/p/cygsimple
export PATH=/c/opt/vim/vim74:"$PATH"
start /c/opt/vim/vim74/gvim `cygpath -w -- "$@"` &
</file>

Don't know.

A windows program will have a different console by default.  A console 
program could can communicate to the same console as it is started in 
unless it uses pty (e.g. /c/windows/system32/ftp).
