My goal is to get UART working on a Sercomm Speedport Plus router. I used a CP210x USB device, connected Ground, Tx and Rx (connections are as shown in Speedport Plus (T-Com) - PC Ekspert Forum) and made sure that Router Rx goes to CP210x Tx and Router Tx goes to CP210x Rx.
Unfortunately, I am only getting scrambled output on PuTTY and/or SmarTTY. What is even more strange is that I get this output even when the Router is not connected to power! Output keeps coming in a non-periodical manner, block after block, with some character blocks being bigger than others. To tell you the truth, the way that output is coming would look normal to me if the characters displayed made sense (which they don't). I have checked the baud rate and this does not seem to be the problem.
I read somewhere on the Internet that it might be that the EEPROM has bricked, but if this was the case, the router wouldn't start at all I suppose. In my case the router starts up, you can even access for a few seconds the web interface via browser, and then suddenly network interfaces (both wireline and WiFi) are cut off.
Does this behavior ring any bell to you? Any ideas/suggestions are welcome.
Thanks!
