When I issue “AT+CGDATA=1”, I get “CONNECT 115200”, followed by about 15 seconds of garbage, and then “NO CARRIER”. What is the garbage data? It somehow causes my serial port to stop receiving data, but only if I am running Windows CE 5.0. Under Windows XP, it works fine. The command and result code look like this:
at+cgdata=1
CONNECT 115200

I have a similar problem with AT+WIPFILE. I get an unsolicited “CONNECT” result code, followed by the contents of the file, “This is a text file.”, followed by some garbage, and then “OK”. It looks like this:
at+wipfile=4,1,1,"./textfile.txt"
CONNECT
This is a text file.
OK
press [Enter] to end
Unders Windows CE 5.0, my serial port stops receiving data after the last double-quote mark. Any idea what is going on?
