1.2.3PC FaxModem Function

1)Transmission function of PC FaxModem transfers an image data to the remote Fax machine by using Class 1 command (EIA/TIA-578) when transmission image data is prepared by Host PC.

2)Class 1 receiving detects ringing from the remote Fax machine and informs ringing detection to the Host PC, and then, Fax machine receives an image data from the remote Fax machine and transfers received image data to the Host PC by using Class 1 command (EIA/TIA-578).

3)Maximum transmission speed:14.4 kbpsa)PC FaxModem transmission (Class 1)
