I don't know of a Forth text specifically on this topic and the 
specification detail thus far would need a little more consideration than 
you have stated thus far.

You need to establish the time-line between both systems to ensure that each 
end of the link will not lock-up waiting for the other end to send a 
specific pattern. That means accepting all communication packages (good and 
bad) and then assessing the validity and meaning of the package once 
received.

You didn't make any mention of check-sums or other error detection in your 
included specification, although it is obvious (from the document you 
reference) that you are expected to use some form of communication package 
integrity checking. Such checksum checking needs to be accomplished on the 
whole of a received package and performed before transmitting a package.

This link, from IBM, might be useful to you.

Incidently, I have noted that the manufacturers of the device has stated it 
is not considered as a medical device so I'll refrain from adding the 
cautions about Safety Critical Systems and Software.
