Hi,
this is my
scenario:
I have a Server Oracle Enterprise Linux 5.4 with a default serial port; in addition I have installed a PCI card with other 2 serial ports.
I need to connect 3 external modems, one for each port.
Following some tutorial, in the terminal window I have entered the commands
dmseg and
setserial -g
The results are:
dmesg | grep tty
Xen virtual consol successfully installed as ttyS0
setserial -g /dev/ttyS*
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
In the tutorial, instead, the output is this
dmesg | grep tty
[ 37.531286] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
[ 37.531841] 00:0b: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
[ 37.532138] 0000:04:00.3: ttyS1 at I/O 0x1020 (irq = 18) is a 16550A
setserial -g /dev/ttyS[0123]
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4
/dev/ttyS1, UART: 16550A, Port: 0x1020, IRQ: 18
/dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4
/dev/ttyS3, UART: unknown, Port: 0x02e8, IRQ: 3
Please, can someone help me to configure correctly the serial ports in order to use with modems ?
Thank You and Best regards
Gaetano
