Re: flexfax: Cannot answer from FAX machine

[Hong Kong Observatory <d1swdev@asiaonline.net>]

Hi,

   I can finally configure the ZyXEL modems to answer FAX machines by
setting the 'ModemSetupAACmd' to 'AT+FAA=0' (setting S7 does not help).
But then I cannot use the ZyXEL modems as data modems (login to the
system through getty). Do you think this is the modem firmware problem or
I can get arround by some other setting ?

   Also I must say thank you for you quick and helpful response !
