First, take your brain out of your skull, and bash it with a mallet...

Nested interrupts are a very bad idea.
If you think you need to do this, you almost certainly are trying to 
run WAY too much code in the ISR.

ISRs should react to the event, and exit.
Let the foreground code pick up the data and decide what to do with it.

Drop your char in a buffer, check buffer status for asserting 
handshake, and bail out.
