Kill -9 the process, after about 20 seconds the system is dead. Open terminal and kill process, nothing will happen, process is still running. Try to close the port - the program will freeze. Go back to settings, change the baud rate to custom and enter 921600 Go to settings, select the cu FTDI device (not the tty) Not actually sure if the problem is with OSX, Qt or my application and due to only being able to use the macbook via VNC I'm not sure of the exact problem that occurs.Ĭonnect an FTDI device to Mac and have it send out data at 921600 all the time I've checked console but it doesn't show anything related to the crash. If I close the port, the application freezes, and within a minute the whole device (macbook) crashes. If however I switch to a baud rate of 921600 then I see no data (maybe the screen is too slow to update, I'm doing this over VNC) but I see the count of received characters incrementing. Description After opening the port, when trying to set custom baud rate (125000 in my case) the setBaudRate () returns true and no errors are reported, but when I transmit the frequency it is 115200 bps (tested with an oscilloscope). If I have a remote device setup to send data out on a loop at 921600 baud and open the qt terminal application at 115200 baud then garbage data is displayed - expected. Qt 4.8.4, serial port stable from wiki, ubuntu 12.04. I have a simple application which opens a serial port with various settings that I can configure.
