If fax functions are not working, you should:
The value 0 is correct for the modem in the Fax setup section of the Fax processor setup form. If there is more than one fax listed in that section, the value 1 is correct for the next fax in the list, and so on. If you see a value of -1 or the value does not match the modem highlighted in the fax setup list, click the Query fax devices button on the Fax processor setup form to correct the problem
Note: You must repeat this process more than once to correct if physical modem changes have been made.
Using the settings in the file, try to send a fax to complete the checking process.
Reset=AT
INIT=ATM0
Faxman should be working correctly. If you are still experiencing problems with Greentree, the cause is either an incorrect Dialling prefix or Initialisation string, which should reflect recommended settings for the internal phone system and modem. Data Techniques Support recommend the best initialisation string is:
AT&FE0V1&C1&D2S0=0,or with hardware flow control: AT&FE0V1&C1&D2&K3S0=0
