Hi Heinz,
Thanks for the response.? I suspect that it may not be so much a problem
with
EPICS base as with my configuration of the ethernet<->serial converter
since I
have a number of other soft IOCs running on different ports of the same
machine.
What I really don't understand is why it is different when the process
is started from
procServ.
Thanks again,
Pierrick
