I have been trying to get some code written in the EPICS state notation
language (version 1.9.2) to run on the Heurikon Baja 4700, but each time I
try and start the sequence I get the following error

scs >seq &scs_st, "T = m3:, D = m3:, F = m3:, I = ins:"
@(#)SEQ Version 1.9.2: Thu Sep 11 12:16:45 BST 1997

task 8097d370 scs_st suspended

The same sequence code runs successfully on an mv167. I am using a version
of EPICS 3.12.2 which has been modified to run on the Baja according to
the recommendations of Dave Barker (LIGO project) and Bret Goodrich
(Gemini project).

Has anybody else seen a problem like this and discovered its cause?
