I’m trying to download my .dwl file to the q2406b via HyperTerminal, but after I send AT+WDWL; the modem replies +WDWL : 0, and nothing else!  
It doesn’t answer on any command, and terminal programm stops… don’t understand, why there isn’t symbols “& & &…” or “$ $ $ $…”  
If I try to send a file by XModem, the process don’t starting…  
What is my problem?

sometimes you have to reboot the module after entering at+wdwl, and then you’ll get the trail of xmodem characters. I don’t know why.

Oh, thanks! I have already found the reason. It was unconnected pin of hardware flow control:)
