| Issue |
Our computer has 4 serial ports and supports interrupt sharing. Does QNX4 support interrupt sharing of the serial ports?
The install script invoked Dev.ser on 4 separate lines, rather than just one line. Will this make any difference to interrupt sharing?
|
| Solution |
Interrupt sharing is supported in Dev.ser.
Use one invocation of Dev.ser specifying the four serial ports on the command line, and it should fix the problem. i.e.
/bin/Dev.ser 3f8,4 2f8,3 3e8,4 2e8,3 |
