This requires a null modem connection from the Heidenhain's DB25 port to a DB9. We were using a DB9 to DB9 adapter that implements the null modem pin swaps. On the Heidenhain side of this, the DSR line must be connected and working! If it isn't, the TNC 151 refuses to think that the computer is present.

 

Parameters can be accessed by pressing MOD repeatedly until you are prompted to enter a Code, which is 95148. Care should be exercised with machine parameters. In this screen, pressing EXT then NO ENT causes a full dump to serial. Pressing EXT and ENT makes the machine look to read them, but sending them as an ASCII file via a terminal program doesn't seem to work.
