INFO: Modem hang-up status codes for class 2.0 fax
ZTN1003
ID: ZTN1003
This Zetafax technical note applies to:
- Zetafax 5 and later.
Summary
Zetafax supports fax modems using the common standards - Class 1, 1.0, 2 and 2.0.In general if the modem reports an error during connection or during the call, Zetafax will display an error message in the server monitor program (and in the server log file) - for common errors this will include a description of the error, while for "unexpected" errors it will give the error code in round brackets at the end of the message.
The list below gives details of these error codes, reproduced from the modem standards documentation, for use by technical support personnel in diagnosing modem problems.
