Honored ContributorHi,
--- Quote Start --- Now I can write to ttyUSB0, but when I use "cat /dev/ttyUSB0" from telnet terminal, and write "at<cr><lf>" to ttyUSB0 from jtag terminal, I receive a lot of "at ok at ok at ok..." from telnet terminal. If I do the same on my Ubuntu PC, I receive just 1 "at ok" as normal. --- Quote End --- I think that you are sending 'AT' commands to your 3G modem.

I can't understand this strange :(:( , please help. --- Quote End --- I don't know such thing. The only way to help you is 'Debugging' by yourself! Kazu
