CUPS, Unix, and OSX

[Mike O'Dell]

If your Mac does not have a built-in modem, the Apple USB modem is quite inexpensive.
It also works with Windoze equally easily and avoids the haywiring with the serial thing.
Fax modems are notorious for using dataset control signals in creative ways and frequently
do not make nice with USB serial converters. T.38 is the most unforgiving serial-based protocols I've ever see, so even if all the signal get there, there is no guarantee of success.

Another other alternative is using one of several services offering fax that can also provide personal fax numbers if you need inbound fax as well as outbound. The cost of these is usually diminimus if nonzero.

To be honest, this was a pretty "hammer and anvil" approach to use when a simple one was available. This approach would not have been particularly easier, possibly even harder,
on Linux or the BSD systems so I would not fault the Mac in particular. This is an example of a Windows-designed device operating in a non-Windows environment and that is often challenging.

Having fought with fax modem hardware for years, and then compounding the headaches with a page scanner, I gave up long ago and bought a cheap'n'nasty fax thing at Costco and when I can't email a PDF, I print it and then fax it with a real fax machine (even though finding where I stored it last is always something of a snipe hunt). "It just works."

Joe, I  admire your tenacity. "You're a better man than I, Gunga Din".

I haven't used a fax / modem in years, yet was surprised to see that while they are still manufactured, the big box retailers no longer sell them.  So, I turned to Ebay.  I wanted an external serial device, thinking that it would be the most versatile regardless of machine or operating system.

For some reason, all the commercial FAX applications for OSX have terrible reviews, so I didn't consider them.  I also wanted to avoid running Windows.

Once the file is edited, one must use CUPS at http://localhost:631 and do some more magic with Unix commands to properly install a generic serial FAX printer driver.  Why Apple couldn't have made the process easier - of course you're not SUPPOSED to use a non-Apple FAX / Modem.  At any rate....

Now I probably cursed OSX by digging under the hood in forbidden territory to make my machine do something Apple says can't be done.  (I've spent a LOT of time in a terminal window in the Unix underbelly of OSX.)

Granted, this machine has performed flawlessly for five years or so now, and even runs Windows XP in VMWare quite acceptably.  But...  Staples had a special a few days ago on a Toshiba with an Intel i3, 4gig, and 500gig HD for under $400.  I should have bought one...
