If I set the baud rate for 57600 and simulate a framing error by selecting 9600 baud on the host, when I return the host to 57600 I can no longer talk to the processor - the poll system call either locks up (if using a timeout of -1) or never returns with any data flags set in the revents flags. Any suggestions?
