[hylafax-users] Can Class 1 Modem Send Fax Tone First ?

[cbain <cbain@acordex.com>]

Dear User Group:

Is there a configuration parameter that will cause a class 1 modem to 
send the fax tone first ? I am using a class 1 internal modem (config 
file shown below) and sending to a receiver that tries to detect whether 
an incoming call is voice or fax by listening for the fax tone first. The 
reciever incorrectly identifies the fax call as a voice call. Using 
another internal modem configured as class 2, the fax tone is sent first 
and everything works OK.
Is there something in my configuration I can change to send the fax tone 
first ? I am using HylaFax 4.1.3 on a Mac OS X Dual processor G4 (Class 1 
modem which fails). The class 2 modem is on a single processor G4 with 
the same 4.1.3 HylaFax.

Thanks in advance for any help

Regards,

Chris
