INFO: Sequence of modem initialisation parameters
This Zetafax technical note applies to:
Under normal circumstances, the settings in the Devices section of the Zetafax Configuration are sufficient to configure a modem. However, some modems and switch/PBX combinations require extra commands, which can be inserted directly into the Zetafax Configuration file, SETUP.INI.
This technical note explains the sequence of these settings.
The following parameters in SETUP.INI can be used to pass configuration commands to the modem
More information on the settings in SETUP.INI can be found in the information file zfax\system\z-db\SETUP.WRI (where zfax is the name of the Zetafax share).
Every few seconds, the Zetafax modem device driver (DEVFC.EXE) checks that the modem is present and working by running the following commands:
- CheckInit1 commands
- General initialisation commands based on the settings in the Zetafax Configuration (setting fax class for instance)
- CheckInit2 commands
When a fax is about to be sent, the Zetafax device driver performs these checks:
- General check (as above)
- General sending-related commands based on the settings in the Zetafax Configuration (setting the modem to send)
- SendInit commands
When an incoming call is detected, the Zetafax device driver performs the following checks:
- General check (see above)
- General sending-related commands based on the settings in the Zetafax Configuration (setting the modem to receive)
- ReceiveInit commands
More information on the modem device driver's settings can be found in the following locations:
