There are two ODBC drivers around. One for our historian and one for Informix from Informix. I should have asked which was in use. Good catch.

I think that an ODBC driver accesses the informix database (with the = configuration data for the historian) through the informix star = software. Please check your system: aw# cd /opt/informix/etc aw# more sqlhosts #SQLHOST NET MACHINE SERVICE PCAT00 olsoctcp PCAT00 star Q3611U olsoctcp Q3611U star aw# check the file /etc/services on your unix box #Informix client-server support star 1541/tcp and check the file C:\WINNT\system32\drivers\etc\services on your = windows system You can use also a port query tool to check all the open doors of your = computer.
