Hi. I have had little success with actually writing and reading to/from a COMx serial port using the above. The laptop is a ASUS 64 bit machine (Win10). I can get as far as configuring the COMx port with no errors. The actual write and read of data does not work. The read I consider is a response to the write (which I cannot confirm). It difficult to trouble shoot. I do get the test unit (a USB automotive OBD2 unit) to work with RealTerm (OK) on COM5. Do people known if I should except this configuration to work ?? Regards JC......
