I have a new PC on which I've loaded an old DOS program. When the program runs, I get this error message: "16 bit MS-DOS subsystem cannot open COM2 port requested by application." I click "ignore" and the program works--right up until the time I try to print a report. I assume it has something to do w/ telling the program where to find the printer--which is attached via a USB hub.
However, if I plug in a parallel cable between the PC and the printer (in addition to the USB), it eventually prints.
Anyone got help for me? Anything I should add to the Basic program (which is the language it's written in)? I'd like it to be able to find the USB connection.
