Hi Greg, The Kermit application closes once the mobile is turned off (using AT+CFUN=0 command or any manually turn off the mobile) and it does not allows to perform any further operation.
Our observation on this is after powering the mobile off disconnect function is called and the file descriptor becomes invalid. But in case of windows OS we don't see this problem after switching off the mobile using hyper terminal and we can still continue with the same hyper terminal for further operations. How can we achieve this in Linux OS? I hope you understood this and please give suggestions on this as soon as possible.

I'm sorry, but I do not understand the problem. The device is turned off, right? What happens to your program then? And please do not post using html email, the linux-usb-devel mailing list will reject such messages. thansk, greg k-h ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
