[BRLTTY] brltty installed on Mac with screen-4.2.1

[Chris Moore]

Hello Cheryl,
When I invoke screen as a normal user, brltty  must be started via sudo in order to work with screen.  But under this configuration the cursor routing keys don’t work.  A brief message on the braille displays says “initializing screen” followed by an error tone.

When I run screen under sudo, I can start brltty without sudo, and the cursor routing buttons work as expected.

What is your experience when you run screen as a normal user?

This really shouldn't be necessary. While I did not have to do anything after installing screen-4.2.1, it still seems to me that this may be a permissions problem. I also run macports but since I already was using a screen installationin /usr/bin, i decided to leave it there for the time being. Of course, one runs macports using sudo so maybe this isn't a big deal but, while I run brltty as root on linux, I would rather run it as a normal user on the Mac.

There was no need to do anything with chmod and no need to run either screen or brltty with su. I am keeping screen-4.0.1 around just for a little while to make sure all is running smoothly and then I plan to delete it.
