[efax-users] efax, /dev/modem and TIFF files

Hello all, I understand these issues may not be related to efax, but it's a start.

Using Mandrake 10.2 with kernel 2.6.x.
Using xsane .97 with Brother DCP7020 multifunction - seems to work fine
Using Intel 536ep internal PCI data fax modem - works fine  via Kppp to connect online  and I can browse no problem. lsmod indicates Intel 536 module is loaded

Now I would like to use fax which I believe is a CL interface for efax. I think I am having  several problems - when using fax send command as root I receive:

error 1. Can't open serial port /dev/modem (this is an internal PCI hdwr modem - no serial port involved - Kppp modem device set to /dev/modem)
This error is at random and I am not able to duplicate it regularly.  Even though I have the modem installed and Kppp configured, I DO NOT use this setup for internet use as I have broadband via LAN via DSL modem for that.
As to error #1 -
Is it possible that Kppp locks this modem and won't release it for  use by other apps until reboot?

How can I tell efax to find, locate, and use  the modem? (efax manual says it defaults to /dev/modem, but not to enter the /dev portion -  I believe it is setup that way)

error 2. /usr/bin/efix: Fri Feb 23 23:40:39 2007 Error: can't read multi-strip TIFF files
/usr/bin/efix: 40:39 Error: missing offset to TIFF data
can't read file Auth300907_signed.tiff.001

I use xsane to scan into TIFF format, but apparently efax needs G3 compression which xsane only does in lineart mode (which I guess the BrotherDCP does not support). xsane scans to a variety of jpeg, png or TIFF formats in  8 or 16 bit with or without compression. Really don't understand it all.

I am occasionally able to send postscript files when I am not having problem #1. Maybe I should concentrate on #1 first?

Any help appreciated
Thank you
