[Bug 58598] Realterm_2.0.0.70 / Crashes on start

[WineHQ Bugzilla]

http://bugs.winehq.org/show_bug.cgi?id=58598

--- Comment #6 from Janne  ---
I tried to make a patch which prevents creation of the PARALLEL_PORTS key into
registry in case where char array devices is empty.

Made two test with patch:

1. Without symlink to lp0. Realterm starts.
2. With symlink to lp0. Key & content are created and Realterm starts.
