On startup, OPRIF 11.6 does not reach the blue sign-on screen. The program locks up and the computer must be rebooted to terminate the program.
TAC I/A Series
The COM port assigned in OPRIF cannot be located. As the result, OPRIF remains suspended in a locked state waiting to initialize the COM port.
This situation typically occurs when OPRIF was previously used for tunneling. A virtual COM port is assigned for tunneling to work.
Prior to starting OPRIF, locate the SETDMS.PAR file in the DMS folder on the hard drive.
Edit the file with Wordpad. The contents will appear as follows:
A=3 B=9600 P=E S=1 W=7 M=N
The first variable listed is the COM port number which OPRIF searches to initialize on startup.
Change the number from 3 to 1 (if 1 is the physical COM port on the computer).
Save and close Wordpad.
OPRIF will now start, initialize with COM port 1, and display the sign-on screen.
