Watch out doing a hard common of the grounds.  It may not turn out 
pretty.  Also make sure there is no VCC routed up the cable.
thanks.

You might well get by with a normal serial DB-9 and some creative cable 
making if memory serves.  At least the 1194 stuff is only 5 signals.  
Some of the jtag pinouts include break and trigger signals though.
