Like Emma, I am having a connect problem, however, it was all working in another place, so I suspect the serial cable between the Digi terminal server is the problem. Nevertheless, here are the relevant software details:

EPICS 3.14.19
RTEMS 4.7
asyn R4-9

in st.cmd:
==========
drvAsynIPPortConfigure("ET-701"."ts-fee-801:2105 TCP",0,0,0)

immediate response:
===================
ts-fee-801:2105 TCP: Link already open!

When the IOC is terminated the Digi shows no connections; when the IOC is started the Digi shows the connection is there. The Digi port is of type "TCP".

What 'link' is being referred to here?
