$Header: /usr/people/sam/fax/port/sco/RCS/README,v 1.4 1994/04/18 18:47:01 sam Rel $
This is a re-write of the SCO README file that I re-vamped from the
one provided by Daniel I. Rosenblatt. I believe that it is somewhat
more generic than the original. I have used the original text wherever
appropriate and made modifications/deletions/additions as I saw fit. I
only refer back to Daniel where I feel his experience was particular to
his installation (marked [DIR]). I thank Daniel for taking the first
shot at SCO, it made my life considerably easier. Contact me or Daniel
if you have any questions pertaining to our comments or how to get
FlexFAX running on SCO.

[ From previous README:
This stuff is from "Daniel I. Rosenblatt" <dir@csn.org>.
Please contact him regarding problems.
]
Stuff to make sure you check:
- all configurable pathnames
- bin/notify calls sendmail, which is NOT configured by default
on SCO UNIX. I tried to use execmail from MMDF, but the
call syntax is so different it would take a considerable
effort to re-write the scripts that do mailing (notify etc).
Since sendmail is available on under SCO, I felt it best to
use it. You may have to load it via custom if your initial
install did not include it. Note that sendmail and MMDF
co-exist on disk and you do _not_ have to use sendmail as
the active mail agent for your system to use it for FlexFax.
- I have provided an rc script for placement as /etc/init.d/flexfax
with links to /etc/rc0.d/K80faxd and /etc/rc2.d/S80faxd.
They are not installed automatically by FlexFAX, so do it
by hand if you want faxd to run when the system boots.
The perms should be 744 with ownership root:sys. Check
the locations of faxd and faxquit in the script. Make
certain you set the device(s) to service in $PORTS.
- faxd/modem sometimes seem to hang waiting for each other; I
haven't looked into this one yet [DIR]
I have not noticed this problem.
- incoming faxes are completely garbled/severely truncated; I
haven't figured out why yet [DIR]
I have not had this problem. Possibly it was due to Daniel's
brand of modem.
- I could not get the SCO getty to leave the line open when FlexFAX
exec'ed it. One problem lies in the /tcb/lib/initcond(ADM)
program which is called by getty. Even after testing replacing
that with a stub that returns 0 (not a good idea to mess with
tcb actually), getty still forced a drop on the line. getty
does this even when given the -h option, which seems to be
only passed on to ct(C).
My solution was to replace the exec call to getty with a call
to agetty. This is found in ports/sco/paths.h:
#define _PATH_GETTY "/etc/agetty"
Agetty is a freely available replacement for getty written by
Wietse Venema (wietse@wzv.win.tue.nl). This worked fine. I
did have to strap out the call to update_utmp(), which broke
on SCO. I have not pursued a proper fix yet; one more item
for the todo list ;-( If you can not find a copy of agetty
on your favourite server---or are just lazy---send me e-mail
and I'll post you a copy. BTW, I have version 1.9 (8/20/93)
and will be sending mail to Wietse to see if this is current.
In the config file I used:
GettyArgs: "-h -t 60 -- - %s,19200,9600,4800,2400"
Other random notes:
- my OS is SCO ODT 2.0; your mileage may vary [BOTH]
- gcc is 2.3.3, libg++ is 2.3, gas is 2.0, ld is from binutils-2.1 [DIR]
- gcc is 2.5.8, libg++ is 2.5.3 [JIS]
- I've got a SupraFAXModem Rev V1.70B-03, not what sam@sgi.com
used (V1.200-H); this might explain the next note and the
problem with incoming faxes being trashed [DIR]
- with my version of the SupraFAXModem, I have to disable adaptive
answering when dialing out, i.e.:
ModemDialCmd +FAA=0DT%s@
if I don't, I get a data connection instead of a fax
connection when dialing another fax-modem to send a fax [DIR]
- I tested the Multi-Tech MT1432L and MT1932ZDXK. Both worked fine
with FlexFAX. I do have a problem with V.17 (14.4k) with the
ZDX, but it seems to be local to my site or the UK and Multi-Tech
has been putting in considerable efforts to figure out the
problem.
Cheers,
Joel
