Jeff,

You should post this one to comp.dcom.modems, not here.

Actually this posting is very pertinent here.  So many games are going
multiplayer that knowing about a new feature like this is important
for players.  

Anyway, here is a question about the modem:  Were you using this over
the internet, or were you just making a local call?  If things are
that smooth over the internet, then in a couple of years all Kali
users (or whatever is used at that point) are going to be really
interacting.  More importantly, in a couple of years you won't need to
use long distance to talk to anyone, everyone will have the modems.

Since DSVD is a protocol between two modems you would not be able to
use the Voice feature of DSVD over the internet.

Internet Phone and other assorted knock-offs are ways that you would
be able to communicate with someone without using 'long distance'.

I agree with Neil. The post is pertinet as long as we do not get too
involved with tech issuses.

I have been considering this getting modem to play DOOM, DUKE and
hopefully QUAKE.  This is exactly the type of information I want to
know. It seems appropriate for this news group.

Or there is a replacement serial driver for Doom and one for DN#D is 
coming next week.  Don't know about others, but they are probably 
around.  It allows you to use a full duplex soundcard to talk back and 
forth.  Supposedly with no delay in the game.  I believe that the 
record/send part is programmed for the Pentium.  Haven't tried it on my 
486 yet, but it sounded interesting.

        I'm not familiar with *how* the DSVD modems actual manage to
transfer the voice stream (although it sounded almost as if the voice
was "packaged" in with the balance of the data stream). I'm wondering
if you had a DSVD -> non DSVD -> DSVD, whether the non-DSVD modem
would preserve the voice portion of the transmission. Specifically,
I'm wondering about the use of DSVD modems across the 'Net. If it
requires "pure" DSVD connections, then Kali / Milk / Game Connection
players would be SOL.

WOW.  I have never heard of that ... WAIT, my Bitsurfr PRO allows me
to connect at 115k bonded, and then pick up the phone and CALL anyone.
The Bitsurfr PRO drops to 56k, and once I hang up it re-bonds to 115k.
Even allows incoming calls when I am bonded ... BTW the calls ARE
crystal CLEAR!

Yes, but that's ISDN. ISDN is great, if:

1) you can get it. Lots of restrictions (3 miles from CO) and tough to get.
2) you can afford it-- it's expensive in most areas, with a PER MINUTE charge in a lot of them
3) your ISP supports it
4) your friends have it too

DSVD is a technology for existing analog lines, ISDN is a whole other deal.

Since the modem would be diddling the data stream _after_ the software was 
building IP frames, the DSVD information would probably not be encapsulated in 
the IP datagrams and would not be delivered.

DSVD modems would probably negotiate non-DSVD connections with non-DSVD modems 
such as those used by internet service providers.

Is the USR DSVD modem available yet? and, if yes, how much it will cost?

I'm planning to replace my old 14.4 modem/fax, so i'm just gathering
infos...

Thanks
