Serial and then some

[Thomas McGrath III]

Hello to the list,

I am stuck in serial land... I don't know enough about it and Rev and 
am looking for a "for the completely stupid" tutorial and guide into 
using serial in Rev and with the upcoming USB externals maybe a fully 
detailed input output tutorial type. I no squat about this topic and 
have had very limited success by tearing other people's examples apart 
to try and understand it further. Sarah's serial stack is the best I've 
seen but it is only one example and with out other examples to compare 
it to I don't really understand the important parts and or the why of 
it.

I need things like:
Do you really need to wait for a response after having sent a command?
Do we know what types of responses will come, what to expect?
Where do we look to know what to expect when looking at a new device?
Are there similarities with devices and responses?
Is there a list of commands to send?
Is there a simple way of understanding the 'why' of these commands?
Why do some devices need certain LF CR etc.?


I have spent days reading stuff on the internet and most concern C# 
etc. and now my head hurts by I don't feel any closer to understanding 
the exact metaphor here.

Any help is greatly appreciated,

Tom
