Hey there! I'm gonna explain a bit of what i'm doing. I'm trying to conect a laptop with a ground control station software to an uavdevboard (UDB4). I want to get data stream through gnuradio, i want to make it serial because of previous work. I can set up the baudrate of transmision at my software (running on windows bdw) and my devboard too, i don't know if that would affect the TTY I/O on Unix (that was a good idea btw, gonna work over that). However, my inteface is an USB/Serial cable if thats what you're asking, i didnt use the RS232 standard, just needed TxRx pins from the devboard.
