Which version of QextSerialPort are you using?
0394a5d33beb7f585b5c9dfac7967e6f67389006 (latest as of jun 13th 2013)
What steps will reproduce the problem?
1. use a Keyspan USA-19HS USB-serial convert
2. read & write several times to the port
What is the expected output? What do you see instead?
The program blocks at qextserialport_win.cpp:320. This is a driver fault. The
program cannot be closed by the task manager, because it is stuck inside the
kernel.
Using other USB-serial converters, one would get an ERROR_INVALID_PARAMETER
(and no kernel dead lock, because of better drivers). I'm unsure why this
happens in the first place, because the manual reset event IS signaled at the
time of the WaitCommEvent call.
What version of the product are you using? On what operating system?
Win8
Please provide any additional information below.
The attached patch fixes the problem (but it is a workaraound).
