I have just installed a Conexant USB CX93010 ACF modem on Windows 7 64bit. This morning I set about trying to configure it to report caller ID. Using Putty I ran the command AT+VCID=1 and lo and behold it returned the caller ID. This afternoon I find that it no longer detects the callerid. I have tried ATZ and then reconfiguring the country in the windows applet. Then running AT+VCID=1 again. nothing. AT+VCID? returns 1 as I would expect. I'm tearing my hair out on this can anyone help?
