You can use inWaiting() to get the amount of bytes available at the input queue. Then you can use read() to read the bytes, something like that: While True: bytesToRead = ser.inWaiting() ser.read(bytesToRead) Why not to use readline() at this case from Docs: Read a line which is terminated with end-of-line (eol) character (\n by … Read more
You can find your Arduino via Terminal with ls /dev/tty.* then you can read that serial port using the screen command, like this screen /dev/tty.[yourSerialPortName] [yourBaudRate] for example: screen /dev/tty.usbserial-A6004byf 9600
I just encountered this problem myself on Windows 7 Professional x64, and a solution that worked for me was to go into the registry and edit the following value: Location: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\sermouse Key: Start Value: 3 Change Value to 4 and it will stop this problem occurring. Here is a list of all valid Start values: … Read more
If you want to use hexadecimal codes, you should add the -e option to enable interpretation of backslash escapes by echo (but the result is the same as with echo Ctrl + R,Ctrl + B). And as wallyk said, you probably want to add -n to prevent the output of a newline: echo -en ‘\x12\x02’ … Read more
I’ve solved my problems, so I post here the correct code in case someone needs similar stuff. Open Port int USB = open( “/dev/ttyUSB0”, O_RDWR| O_NOCTTY ); Set parameters struct termios tty; struct termios tty_old; memset (&tty, 0, sizeof tty); /* Error Handling */ if ( tcgetattr ( USB, &tty ) != 0 ) { … Read more
I tried so many solutions on here that didn’t work for me, only displaying some of the ports. But the following displayed All of them and their information. using (var searcher = new ManagementObjectSearcher(“SELECT * FROM Win32_PnPEntity WHERE Caption like ‘%(COM%'”)) { var portnames = SerialPort.GetPortNames(); var ports = searcher.Get().Cast<ManagementBaseObject>().ToList().Select(p => p[“Caption”].ToString()); var portList = … Read more
I hear a lot of good things about com0com, which is a software port emulator. You can “connect” a physical serial port through it, so that your software uses the (monitored) virtual port, and forwards all traffic to/from a physical port. I haven’t used it myself, but I’ve seen it recommended here on SO a … Read more
ah… it is much easier than i though. ls /dev/tty.* ls /dev/cu.* will list /dev/tty.usbserial-A700dYoR /dev/tty.Bluetooth-PDA-Sync /dev/tty.Bluetooth-Modem /dev/cu.usbserial-A700dYoR /dev/cu.Bluetooth-PDA-Sync /dev/cu.Bluetooth-Modem
this is something I did and worked out for me so far: import os, pty, serial master, slave = pty.openpty() s_name = os.ttyname(slave) ser = serial.Serial(s_name) # To Write to the device ser.write(‘Your text’) # To read from the device os.read(master,1000) If you create more virtual ports you will have no problems as the different … Read more
We have moved to java-simple-serial-connector which seems to be very stable and comfortable at the current release 0.9.0. For now, it works on windows and linux systems. We use it for modem interactions.
