Various EM7455 devices coming from different brands and sale channels are often configured differently. They come with different firmware versions installed, different settings, and some ports can be switched on or off. Sometimes COM ports are off when you get the device, but it is useful to have a COM port enabled in order to do extended diagnostics and alter some settings that are normally not possible.
So what do you need to enable the COM ports for your EM7455?
The instructions below are for Windows users. If you can easily find your way in Linux, just skip it and note that you only basically need to run ./swi_setusbcomp.pl –usbcomp=8 to enable COM ports. Follow this link for more info: http://www.mork.no/~bjorn/MC7455.txt
