there are circumstances under which a guy would want to use the part the OP specified. (1) He's building ONE of what he wants, and he already has the parts, (2) his lab assignment was to do THAT, and not something else, and he's wanting some guidance as to where to begin (not the best motive if he intends to learn anything) (3) his boss told him what to use.

Already having the parts is a powerful motive if you're going to build exactly one of something and have to finish it this week. That's particularly so if it's already Wednesday.

One of the best ways to learn what a bad design is, is to build and use one.

However, Marek Swierzy hasn't been back for a few days now and hasn't indicated why he can't use two stop-bits. Has he been spooked off by yet another tirade about why his choice of parts is wrong?
