We have a problem like yours, we have a VAX 6310 running Ultrix 3.0, and if we
put some modems in the serial ports then a while later the machine completly 
hangs.  

 IS THIS FROM ULTRIX  ??????
              ^^^^^^

 We ask to our DEC representants and just said tha we must change our version 
to ULTRIX 3.1, then we receive the upgrade, but it doesn't works (a sintax
error when compiling the new Kernel, so we can't build the new  Kernel), the
problem is in the gfs_data.c archive, we told them and just send  us 
a new copy of it that doesn't works either.

  Help me please......!!!!


 Thanks !
Atte.
