I had to set minicom to disable hardware control and the looping worked for me, as well as cross connecting 2 Raspis together over UARTs. The port is an EIA/TIA-232 async, serial, full-featured DTE connection with hardware flow control, and an RJ-45 connector. 2. 2 Flow Control. --flow | -f Defines the flow-control mode to set the serial-port to. 3V) levels, meaning you cannot use a standard serial or USB to serial cable: it will fry your board. By default, minicom will not wrap longs lines of text, which causes them to run off the edge of your terminal screen. The control unit can disable SDMMC_CK generation when the bus is idle. Communication Mode Selection The UART controller supports a number of communication modes. Configuration is similar for other target boards. 1 Answer. Improve this answer. If I construct the script to exit and leave minicom running, minicom gets timestamps after the script completes. To disable flow control on some ports, while leaving it enabled on other ports, just disable it on the individual ports you want to exclude. 10. Step 5. For example, AT+CMGS=1. c and you'll find an array named "speeds". Connect a USB Cable ¶. If this bit is set, enable flow control of input based on the RTS wire (RS232 protocol). If I do this from a terminal on my host machine (like gnome-terminal) I can hit "Ctrl+c" and it will exit and give me another prompt. So you can only do software flow control.
