Or even ducks the issue by all-balling the identifiers. Those most often 
encountered looking like a usb key gismo and soon find the trash can.

But since fdti is the only maker of seriel adaptors that actually works, 
proliic tried but failed miserably, I see no reason not to reach thru the 
adaptor and see if its actually a braille device, rather that blindly 
assuming it is when there are many other often legacy devices that need 
the adaptor. The cm11a to control your lights and appliances interface is 
likely at least 30 years old, and the protocol was known in the mid 80's. 
I wrote software in the late 80's to do that from a trs-80 Color Computer 
running os9-level one, then jim hines and I moved it to amigados using 
ARexx and sold registered copies of it for a few years.  Called it ezhome 
based on something else we wrote called ezcron since amigados had no cron 
utility. We gave that away.

True Tomas, but my attempts to install w/o it have all failed as it will 
not reboot without it so a reboot turns into a new install, 20 some times 
now, which I'm sick of doing, hence my questions that keep harping on 
getting rid of it gracefully AFTER the install. Basicly, whats done 
should have an undo method and I will keep asking until the magic phrase 
comes out of someones fingertips. In the meantime I am reminded of it by 
the need to reboot weekly in order to have a usable machine.

Take care and stay well, Tomas.
