Re: Check Device status

[Tony Eyles]

I tried that :(

FILESYSTEM is suppose to check devices as well.  But is ttyUSB0 too devicie?

Hi Tony,

Have you tried FILE, instead of FILESYSTEM?

check file USB_Serial0 with path /dev/ttyUSB0
    if not exist then alert

Cheers!

Is there a way to check if a device is available?

For example checking if a USB Serial device shown in the system as /dev/ttyUSB0 is actively seen by the system?

I have tried

# check for USB serial adaptor as USB0

check filesystem USB_Serial0 path /dev/ttyUSB0

    if changed fsflags  then alert

and

# check for USB serial adaptor as USB0

check filesystem USB_Serial0 path /dev/ttyUSB0

    if not exist then alert
