[hylafax-users] Decrease error check will prevent T.30 T2 timeout error ?

["George H" <george.dma@xxxxxxxxx>]

Hi again,

After switching my US robotics modem (U.S. Robotics 56K FAX EXT
V1.915M) from Class 2 to Class 1 I started getting some odd errors
(maybe it was just bad luck I don't know) on Hylafax+ 5.1.2.

For 1 certain fax I got "T.30 T2 timeout, expected page not received"
twice and then "RSPREC error/got DCN"  I looked at the TIFF files , it
seems that the first 2 times only the first page came through. The
second one looked like the first page and some black lines at the end.

Snips of the log files are as follows:

'recvq/fax000000102.tif' 'ttyS0' '000000146' 'T.30 T2 timeout,
expected page not received'

When I made some searches on this problem I saw posts of people
talking about reducing error checking or even turning it off
completely. I don't know too much about this stuff so I wonder if this
is a problem from the sender or from my end or from just crappy phone
lines.

Below is the full log of the bad fax (got that twice and then I got
the "RSPREC error/got DCN" notification which is even longer. Any
ideas or help is appreciated.
