I think I need some education on Serial ports.
I purchased a USB to Serial cable. I installed the driver for it. It now comes up as COM3 on my PC.
If I connect the Tx and Rx to the Domino’s COM1 in and out pins, will communication work? I believe my cable outputs RS232, is that right? But the COM1 on the Domino is TTL UART?
Do I need to buy a “TTL-232R-3V3” as stated on page 76 of the “beginner’s guide to NETMF”, or can I still use the cable I bought with some minor mods?
When I tried the example on Page 76, which sends text, I received heaps of weird ASCII on my Term program.
I also tried the loop-back example on page 78, with a wire connected from COM1 in to out on the Domino. The code just sits to the “UART.Read” line. Why does this occur?
