This would make things worse. When would one know that a command is timed out 
and really lost and needs to be reissued, when do one know that you have 
every OK one should have gotten? This would also add a lot of latency on 
answering a phone call. So, yes it would be possible, require to write a lot 
of code to make it bullet proof and can be totally be avoided by sending 
something that will never ever generate a response and will always wake the 
modem up.
