This may be a naive question, but: is it possible to use more than one
modem at once? That is, I am thinking of opening a bbs, & if I had two
or more modems [internal or external], would they work at the same time? I seem
to remember that the odd & even serial ports share interrupts [ibm]. 
Thus, assuming the multi-user issue were handled [maybe Unix], how would
one go about handling the modems?

Any info  appreciated. 
Thanks

In doing some testing, we've connected two ZyXEL 1496E modems together
over standard phone lines at the 16.8K ZyXEL protocol and SLIP, and 
are getting with a 500K file, FTP transfer times of:

	w/no error control or compression	1.5Kb/sec (~1500 cps)
	w/error control and compression		2.9Kb/sec (~2900 cps thruput)

We've also fired up some X11/clients remotely and that's proved to be
quite usable, even for graphics.  Granted, it's no 10Mbps ethernet, but
it's usable for most things.

ping (icmp packets) times are slightly inflated with compression turned on, 
varying like so:

PING s-taliesin (192.100.159.6): 56 data bytes
64 bytes from 192.100.159.6: icmp_seq=0 ttl=255 time=180 ms

--- s-taliesin ping statistics ---
10 packets transmitted, 10 packets received, 0% packet loss
round-trip min/avg/max = 180/202/215 ms

Without compression, we're getting:

PING s-taliesin (192.100.159.6): 56 data bytes
64 bytes from 192.100.159.6: icmp_seq=0 ttl=255 time=153 ms

64 bytes from 192.100.159.6: icmp_seq=9 ttl=255 time=153 ms

--- s-taliesin ping statistics ---
10 packets transmitted, 10 packets received, 0% packet loss
round-trip min/avg/max = 153/153/153 ms

Although we loose a little on Interactive turnaround time, the
overall throughput with compression (v.42bis) is preferable.

I've always been able to find someone to give me a hand; however, they
weren't always able to go as far as I'd like.  For instance, Supra
charges $20 for a cross-ship RMA -- something that is SOP for free
with every other computer company I've ever dealt with.  This wouldn't
be a problem, of course, if the modem worked, but when it fails, I
can't afford to be down for the week it might take them to fix it.

Why do you instantly jump to the conclusion that they are "unethical"?  How 
can you possibly know the rep knew "full well" that it wouldn't happen?  
Believe me, sales reps are the *last* to know.  Really, now!  I'm not here
to defend Supra, mail order, or big business, but let's back down, OK?  If
you're not in a retail business (especially one that involves mail order),
you have no *idea* of the slings & arrows of outrageous fortune that always
stalk you. 

All right, I'm one of the lucky ones.  If I was in your shoes, no doubt I'd
be muttering by now, too.  In fact, businessfolk have a damn sight lower
threhold of tolerance than lay folk.  But a businessman can also appreciate
the hell that other businesses go through when they're a victim of their
own success; it's happened to me, too, and you scramble like hell to make 
it right.  I bet a lot of competitors are looking at Supra and sighing,
"Gee, that's a problem we WISH we had!"

From uunet you can get the same price on stand alone, and $699 for rackmount.
a copy of ftp.uu.net:/uunet-info/modem-prices has a full pricelist of

I'm looking for Dos or Windows communications software that takes into

a package that easily handles:
 
          Hotel "outside line" codes
          Long distance company access numbers
          Telecom carrier PIN numbers
          Area Code dialing requirements

I've only seen one package that even attempts to address any of these

I know packages with script languages can be tortured into doing these

I was using Telebit T2500's GF7.00 locked at 19.2K.  The effect was not
major but definitely measurable and reproducable.  I've misplaced the
actual numbers (test was run 2 years ago).  But as I remember it was
much more pronounced on V.32 than V.22bis, and varied according to
transfer protocol being used.

And since you mention TCP/IP, I left V.42bis on as it seemed that the
compression of the IP headers versus the additional latency was just
about a wash (as measured with repetitive ping tests), and the SMTP
and NNTP data benefitted a lot.  FTP transfers of compressed files
were slightly degraded but not enough for me to drop the link and
reconfigure.  Overall quite effective at compressing data and getting
out of the way when not needed as compared to MNP5, as you state.

The T2500 is an older design.  Currently I (personally) use a
WorldBlazer and haven't run any real tests on it or my previous
T3000.  My understanding is that these newer platform Telebits
have significantly more grunt power.

My INIT-String is: ATB0E0Q0V1X4\N3%c1\L0\J0\Q1\V1S0=0

The old MNP4 modem works fine (without MNP5 commands).

If it is possible to have a customised message instead of canned music or
whatever they put on the line when it is switched over, it might be possible
to fool the modem at the other end with a fake carrier. Fooling the modem
at your end could be done whatever the telco equipment does. Can it be done?

Boy, is my Plus gonna be mad.  It thought it COULD  do RTS/CTS handshaking,
and now it finds out it hasn't been making all those calls after all!  :-)

Actually, the Plus can use the hardware cables, and does do hardware
handshaking--at least some Plusses do, so maybe earlier models had a setup

well, V.32bis with V.42 (ignore data compression for the moment), the
upper limit on throughput is going to be somewhere in the neighborhood
of 1724 cps (give or take...that's an estimate based on calculations
posted by Toby a year or two ago).  1724 cps w/ compression completely
turned off.  with V.32bis, V.42/V.42bis, and pre-compressed data, I
normally see about 1650 to 1700 cps (yes, that's for very large Zmodem
transfers).

in other words, from the estimated maximum, I might see a loss of no
more than 100 cps (I've never gotten worse than about 1640 or so, at
least, not when I've been paying attention), and normally only about
24 cps (1700 cps is probably the most common number I see on transfers,
and 1640 cps is usually only on long distance calls).  keep in mind,
this also includes any loss in speed due to line errors, etc.... 

hmmm, doesn't sound like my modem is causing any noticeable effect on
the throughput!  :-)  nor are the various different brands of modems
on the other ends of calls I make.  this also applies for other brands
of modems I've tested in my former employer's network design lab.  no
significant degradation between V.42bis being turned on/off during the
transfer of compressed data --- just exactly what the specs tell us
should be the case to begin with.

so yes, I'd say that if you're seeing much in the way of degradation
as a result of V.42bis being turned on, you do have a problem with your
modem.  contact the vendor and get help or get them to fix it,
(depending on whose problem it is).  if, as you suggest, the modem
doesn't have the CPU power to handle V.42bis, and so it's getting bogged
down, that sounds like a major design flaw to me.  complain fiercely.

my modem is a USR DS, what's yours?  please let me know, so I can make
sure nobody I know buys that brand in an attempt to save a few pennies.
