How does faxing work?
When I set the S0 command, store it with &W; then send “ATZ” to the modem, the command goes back to
the default of 0?
After I set the E and &D commands followed by &W, it looks to be stored okay, but as soon as I recycle
power on the unit the E and &D commands get set back to default of E1 and &D2.
After I set the Q, V, and &S commands followed by &W, if I recycle power or send ATZ to the modem the
settings will get set back to default.
What is the max supported serial baud rate?

The CDMA modems only support Class 2.0 Group 3 faxing.
Need fax services setup on the account.
Need fax software that supports the modem; e.g., WinFax Pro v10.0.
Need to set ‘AT+CICB=1’ for modem to answer in fax mode.
This is a bug in the modem. S0 will store just fine, as long as “ATZ” doesn’t get sent to the modem.
This is a bug in the modem. These commands will not store correctly. If modems are powered back up and
an “ATZ” is sent to the modem, then &D and E will load to your stored settings correctly.
Firmware versions 210 and above fixes the storage or the E command.
Bug in the modem. These commands will not store.
