fax receive script ?

• Messages sorted by:[ date ][ thread ][ subject ][ author ]

Here comes the diff for how I patched ../voice/vgetty/answer.c
to enable my Rockwell get fax/data properly after being in voice mode.
Sorry it contains the comment I put in for myself.

The idea is that you play with autodetection only if answer_mode
is undecided before, i.e it is ANSWER_DATA | ANSWER_FAX .
If answer_mode is already decided (i.e ANSWER_FAX or ANSWER_DATA only)
then the code switches off autodetection (+FAA=0) so +FCLASS state cannot
be played with.

With my modem incoming fax always led to the ANSWER_FAX (only) mode
to be set, so setting +FCLASS=0 led to failed fax reception.  

I should note, that (if I remember correctly) forcing autodetection
in config file (so that everything goes through ANSWER_DATA | ANSWER_FAX
branch) still leads on my modem to fax failure. Which seems to mean that
it not only cannot autodetect in +FCLASS=2 mode, but cannot autodetect
at all after being in voice mode. Well ... it works fine in most of other
aspects.
