Hello,

I am running VEE version B.01.00 on a Sun Sparcstation 20.  I have a direct
I/O object wrapped within a UserFunction, which is called many times.  Most
of the time it works fine, but every once in a while it produces 405 errors.
I send the following dvm commands in the direct I/O object:

reset
preset 1
func (dc voltage
aper  (1/60)
lfilter
azero
fixedz
ocomp
delay (auto)
slope
level
timer
nrdgs (1)
trig
tarm 1
read (for number of readings)
preset 1

I would appriciate any suggestions.  Sorry about the partial message
earlier.  My fingers got out of sink with my brain.
