This doesnít really answer any of my questions, but at least they replied. if any one could tell me how to test the serial port is working correctly or what the problem is, I will be very grateful
Thank you for your interest and using our kits.
Yes, the cable must be full connected and connected "pin-to-pin" because
the kit use the "handshaking" signal lines and not the normal RS232
Please check the following things, these are the most common problems.
- The voltage, supplied to the K8048 must be at least 15V (=12V
- Serial port is not 100% IBM compatible (new PC's may have different
- Cable is not correct
- Kit has an assembly error ?
