3.8 ASCII-Fax Function
modem starts dialing the stored number.
The converting can take some time (about 30 seconds to 1 minute). If the fax has
been sent successfully, you receive the hang-up message (class2) and OK or
ERROR as a response. If the fax could not be sent, there is no automatic repetition.
A new attempt has to be initiated by the PLC.
Please use the FPWIN Pro Library "Modem" for PLC programming support.
