Question about serial ports
Posted on 2002-05-09
I bought a Royal postal scale that downloads the current postal rates from the internet. The scale is connected to the pc with a RS232 Serial Cable. When I attempt to download the current postal rate from my pc to the scale; I get a message that the download failed.
My OS is Windows NT 4.0. Serial Port 1 is set to Com 1 & Serial Port 2 is set to Com 2. My modem is set to Com 3. In the setup software for the download; I am supposed to choose the com port that the serial cable is connected to. I've tried Com 1 & 2 and I get the same message.
I went into the bios to see if the serial ports were enabled.
They were set to Auto. Tried to download on these settings first. Would not work. I then changed serial port 1 to Com 1, etc.
Can anyone tell me what I am doing wrong?
