Hello list,<br>
<br>
I am experiencing a very strange problem with MC7304. Randomly (like in <br>
1 of 3 instances), when initializing the WAN connection, the modem setup <br>
routine fails on the--wda-get-data-format command, and then the <br>
completion of the initialization just fails. For now, we have just been <br>
detecting this and then reset the usb port and rerun the whole procedure <br>
at regular intervals until it works, but that is not a permanent <br>
solution. The wda-set-data-format also fails when get does.<br>
<br>
Have been googling 'lightly' without any obvious success. I was hoping <br>
some of you experts on this list just pops up and say 'you need to do <br>
this' before we start spending to much on digging very deeply into the <br>
issue :)<br>
