Unfortunately, the issue that exists is a known conflict within the Now Software, which apparently sends AT commands too quickly to the modem to get what it deems as a valid response. Thus, the software does not believe that the modem is responding. The Now Software Manual suggests trying to change the initialization strings to the following settings if users are experiencing problems:
Supra Modems.
Replace all strings with the following:
Initialization: AT&F1
Prefix: ATS7=30DT
Suffix: ;
Hangup: ATS7=50H
Currently, however, there is no known fix or patch released by Now for this problem.
Machines Affected: All
