compumotors

[wright@luke.atdiv.lanl.gov (Rozelle Wright)]

I have been helping with an old application at Boeing
which has been ported to EPICS 3.11.  They have two
Compumotor 1830 stepper motors which worked fine a couple
of years ago with a much earlier version of EPICS and now
no longer work.  The problem turned out to be a change in
the number of parameters for the driver.

In the routine drvCompuSm.c, the previous calling
sequence was 
compu_driver(card,value_flag,arg1,arg2).

The correct calling sequence now is
compu_driver(card, channel, value_flag,arg1,arg2)
