Re: Liberty-eiffel Digest, Vol 56, Issue 1

Hi Paolo,

nowadays, there's more than meets the eye when talking about serial 
communications.
Most such communication happens over virtual devices nowadays (via USB or other 
interfaces). Even when you look at SBC's like Arduino, Raspberry Pi, etc., this 
is the case.
Whipping up some code to support all of this will prove to be a project that, 
if really seen through till the end, might take an entire year or even more. Do 
you really want to do that?

Having said that, as my serial communication needs centre around SBC's, GPS 
receivers, and other sensors (and as my personal projects involve OpenGL too, 
all of this bare-bone without any OS), I would never use any Eiffel compiler to 
push my projects forward.

In my point of view, Liberty as a project would gain much more in the long run 
by bringing ET's error count down significantly, by offering/wrapping a really 
generic GUI, and to make the current database offering more generic.

Just my 0.02 €...  :)

Hans
