[Info-vax] C_TEST_ROUTINES.C link problem

[eh]

Hi,

I'm still have problems to reproduce the steps documented in "Debugging 
a Device Driver":

After the connection of the two machine via debug/keep as described,

the "set break" command fails:

Do I need special options in the link step?

I'm helpless!!!
