comment Interpreting sensor names
Yes. The thread is mine :-). And since February 2013, I still have just a few names.

comment What is the minimum delay between two consecutive RS232 frames?
That is true. I am having trouble with the transmission. But that does not mean my receiver is perfect. I am sure there are problems that I have not detected. I did not know of the 16x receiver clock. I had thought of something similar, but did not implement it as it would take a lot more hardware. I might try 4x.

comment What is the minimum delay between two consecutive RS232 frames?
Using an FPGA, I have little control of the raise time or the fall time. Also, I am not attempting to implement the EIA/RS232C specification. What I can reasonably do an an FPGA is a serdes. Example code provided by the vendor works just fine - so I rule out analog trouble. Although example codes do not dump single characters as fast as the hardware possibly could.

comment What is the minimum delay between two consecutive RS232 frames?
Okay, I had a free running baud rate generator. May be I should try to reset the counter in the generator on detecting a start bit. But this is not my problem - the computer is going out of sync, not the receiving FPGA (not stress tested yet).

It just occurred to me that I get the same problem whether I use the IO pins to connect to a USB TTL UART module (ebay.com/itm/…) or the onboard USB UART. Can I eliminate signal jitters?

This is my first revision of the UART. I have not yet implemented a FIFO or anything fancy. Just a Serializer and Deserializer.

comment What is the minimum delay between two consecutive RS232 frames?
This makes it look easy to get out of sync if I have one start and one stop bit. Practically, my stop bit is a little bit longer as the serializer it loads the next byte in. I used a logic analyzer. I do not have an oscilloscope :-( But the FPGA and the board are designed to operate up to 400 MHz (digilentinc.com/Products/…)

@user13267: I may also suggest that you report this to the developers. They may modify the code. This would benefit everyone and you will not have to patch and compile every version they release.
