Well, after you posted that those values were not evaluated, I went back and removed them it is still working okay. So the line I have now is: "serial1=directserial realport:com1" I know I tried that last week and it would not work for anything. And now it is. ?????

> startbps:9600 parity:n bytesize:8 stopbits:2 Um, these values aren't evaluated. Huh? It does not work without them and does work with them.

Thanks to h-a-l-9000 and Harekiet for your help. I have it working. In the config file I had entered: "serial1=directserial realport:com1" and was having no luck getting it to work with the time clock it was connected to through a modem. I had set up the USB/Serial converter in Vista to com1 as: …

Thanks for the reply. I'm not at that work computer now but I brought the cable home to try on my PC at home. It's running XP and does have physical serial ports, Com1 & Com2. I installed the drive for the USB to Serial cable and it lists it in Windows Device Manager as being Com3. When trying your …
