Is it possible to set serial port parameters (baud rate,flow control) over the air, or can this only be done from the port itself?
We have a little TCP utility that we use to send remote AT commands and to launch a download-over-the-air process, and the problem is we want to do a remote firmware upgrade but updating the firmware seems to set the UART parameters back to the defaults of 115k baud with flow control, which is not what we are using.
