Code port1 : <port neg> / port = lpt1 / subport = data / items = ("00000001") </port> Error: Unable to obtain the address for parallel port 1. Code port 2: <port neg> / port = lpt1 / subport = data / items = ("00000001") </port> Error opening \\.\COM7: System error 5: Access is denied. Line 100, File win\SerialConnection.cpp How to fix this?

E.g. have you verified that your parallel port is actually registered as LPT1 on your machine? You can check that via the system's device manager ( <port neg> / port = lpt1 ... </port> I would also recommend testing communications / proper settings via Tools -> Parallel Port Monitor... See the "How to Use the Parallel Port Monitor Too" topic in the documentation for details.

The <port> definition you posted pertains to a parallel (LPT) port, not a serial port. The NBSPortDriver you mention is -- as far as I can tell -- a driver installed by Presentation (cf. https://www.neurobs.com/menu_support/menu_forums/view_thread?id=3711 ; https://www.neurobs.com/menu_support/menu_forums/view_thread?id=5529 ) and as such is unrelated to Inquisit or the system's available hardware interfaces. Whether that driver can cause interference, I do not know.
