Hi, We are having trouble with detecting the serial port in Fedora Core 6. When I type the following command: setserial -g /dev/ttyS* I get the following message: Cannot get serial info: Invalid argument /dev/ttyS1: No such device or address /dev/ttyS2: No such device or address /dev/ttyS3: No such device or address However I tried this on two other machines running Fedora core 4 and Fedora core 5 and both were able to detect the serial port A typical result is /dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4 /dev/ttyS1, UART: unknown, Port: 0x02f8, IRQ: 3 /dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4 /dev/ttyS3, UART: unknown, Port: 0x02e8, IRQ: 3 We are not sure if this is a problem with Fedora Core 6. Does anyone know how to fix this issue on Fedora 6? Any help would be greatly appreciated. Thanks. ____________________________________________________________________________________ Cheap talk?
