This is my tale of the Hayes 56KB modem.  I read the
K56FLEX.TXT account that I found on the OS2 Shareware BBS
midway through this effort, and got somewhat discouraged, but
I persevered, and it worked out OK.

I bought a Hayes Accura 56K internal FAX Modem, Part Number
08-02974 about ten days ago.  I read the instructions - no mention
of OS/2 other than to say that Windows 95 and OS/2 support 8 COM
ports.  That was opposite a page that showed how to move the jumpers
for different COM ports.  

Well, like a dope, I decided that Plug & Play wouldn't work with
OS/2, and moved the jumper off the Plug & Play place and set the
thing up for COM2, which is what I had on the previous 14.4 KB 
model.  Put the thing in (each installation required crawling under
the desk, disconnecting all the cables, schlepping the tower out
and standing it on a chair, etc, etc, and then putting it all back 
together) and fired it up.  Didn't work.  DOS couldn't see the thing.
OS/2 couldn't see the thing.

Put the 14.4K card back in.  IT DIDN'T WORK!  Enough for one night.
$150 sunk in this thing, and now my baud rate was zero.

The next day, for no reason that I can fathom, the 14.4K card worked
again.  I didn't change a thing, but it came back.  Bad karma, maybe.

Well, let's give it another try.  Put the 56K back in, still with
the jumper set according to the instructions in the book.  Maybe I 
should try the install.exe program under DOS.  It refused to put the 
program it was installing where I wanted it, and insisted on putting it
on C:.  OK, let's humor the thing.  Put it on C: if you want to.  All
the install program did was to put a program called SETCOM16.EXE into
C:\SETCOMM.  When I ran SETCOM16.EXE, it said it couldn't find the
Plug-n-Play modem.  

AHA!  The light came on.  I put the jumper back where it was when I took
the modem out of the box, booted up DOS, and ran SETCOM16.  This time it
happily set the modem to COM2, as if it had read my mind.

Boot up OS/2.  Light up Internet access.  Ilink/2 hooked me up at 38.4, much
nicer than 14.4.  Of course, I had forgotten to reconfigure ILink/2.  Take
the connection down, configure the bps (not baud) to 57600, and try again.
The Netcom server in Vienna, VA took the connect at a nominal 57600 rate.
I have no way of knowing the true speed achieved, but it is definitely
MUCH faster than before, and seems fairly close to what I have seen on
ISDN elsewhere.  It looks like our telco lines here in Northern Virginia
are pretty clean, so the results (as of ten minutes of use) look pretty
satisfactory.

BOTTOM LINES:

Get the upgradable Hayes

Take it out of the box

Put it in the slot

Use the SETCOM16 program to configure it.
