COM port framing errors

[bgaughan]

When running COM port loopback I am seeing "Framing Errors". Even with CTS/RTS diabled.
What is this telling me? Stop Bits not being seen?

A framing error occurs when a data frame is too long or too short and can be caused by a number of things;

• A mismatch in serial characteristics between the two devices
• Bad cable (this shouldn't be applicable in this case if you're using our loopback plugs)
• Bad serial port
• Electrical noise
• A mismatch in clocking speeds between the two serial devices

BurnInTest will open the serial port using the settings of 8 data bytes, no parity and 1 stop bit (8-N-1). If the framing errors are occurring at high baud speeds then try lowering the speed.
