Dear All, After connecting USB to Serial connector to the port of friendly ARM board,I have given following command to access the device, #microcom -s 115200 /dev/1-1 It respond's as, microcom: can't tcsetattr for /dev/1-1 for USB: Inappropriate ioctl for device How can I overcome with this problem. With Best Regards.
can't tcsetattr for /dev/1-1 for USB
Are you sure this converter is /dev/1-1? Had to do a few experiments: On a netbook my USB to serial converter is ttyUSB0. On a mini2440 it doesn't register. I suspect that my kernel doesn't have serial converter support built-in or as a module. Just for my information, is using one of the other three com ports on the mini2440 not appropriate for your application?
actually i am using usb port .i have connected usb gps modem. to it .i got the problem which i had mentioned above . how to configer usb to serial converter ? For more clarity I have uploaded the "USB debug message screen shot" while connecting the USB to the friendly arm port?
I see where you are getting the 1-1 from! Try dmesg, note the last few lines, then plug the device in and demsg again and send a picture of that output.
