Ticket #7398 (closed defect: fixed)
Serial Port transmit hang after sending break signal
|Reported by:||sundarapandian||Owned by:|
I have created COM1, COM2 serial ports and attached them to the host device /dev/ttyS0 and /dev/ttyS1, respectively. When I open any terminal program (teraterm, hyperterminal etc.) I am able to use the serial ports to send/receive data from and to the device connected to the physical port. But if I send a BREAK Signal, the transmit functionality won't work after sending the signal.
Steps to reproduce:
- Create Serial port COM1 and link it with host port say, /dev/ttyS0
- From Guest OS open terminal emulation program and check if your Tx/Rx works fine
- From terminal send BREAK (if using TeraTerm use Alt+B to send it)
- Check if Tx Works now!
