Yes folks this is done by IBM in the AIX for the RT. Its made by
defining one mapping for incoming characters and one for outgoing ones.
This is enabled on a port by port basis where the mappings are plain
textfiles with 256 lines and two columns. 
This simple mecanism enables terminals to be intermixed and still use the
same (internal) representation of 8 bit character sets. 
Of cource it does not handle 16 bit characters and it does increase the
loading but it io really a nice feature.
You could wish terminal maker to do this too ..(Texas did in thier 745
remember ??)
