Re: [hylafax-users] EOP between 2 hylafax server with Multitech 5656 modem

["Emmanuel RIZZI" <erizzi@xxxxxxxxxx>]

Hello

I've tried this setting without success.

This is my modem informations:
ATI0
MT5656ZDX

ati3
ACF3_V1.702A-V90_P21_FSH

atI6
RCV56DPF-PLL L8571A Rev 47.00/34.00

The chipset is made by Rockwell, is it OK to configure it as "lucent-mt-2"?

Thanks
