Hello Everyone,
I have a serial port application that routinely fires cmds and awaits data to return from a number of serial ports. Most of these are connected via serial/usb converters like the FTDI adapters that are available. The problem I sometimes run into is one of the serial devices gets ‘hung-up’ or the connection is broken (cable disconnected, etc.). When this happens, the app becomes unresponsive and the user must force-quit.
Can anyone suggest a method of using a watchdog or some other lightweight way to detect if the port is no longer working and allow me to close the port with grace?
Thanks, Sean
