So, I'm not a guru, I'm just an application end user. We have been using a serial scanner for two years and a custom Membership software package. It scans a drivers license and popualtes the membership field. all is well until we have to replace the computer and it has no serial port. I buy an USB to serial cable and drivers and install. It grabs Com3 and almost all is well. Sometimes the scanner doesn't work when we launch the applicatition. We close the app, pull the USB cable, put it back in and re-launch the app and it works. It still grabs the same port and same settings. It will usually work until we close the application again and then the problem is back. Is there a better solution?
