I've entered this message in many different networks today because I'm
so desparate for help with this problem.  If you've seen it aleady
elsewhere, please forgive me.


If anyone could possibly help me with the problem I'm about to
describe, please do.  Thanks.

I recently bought an Intel 14.4 EX modem.  It has everything that
a high speed modem should, except there's one problem.  I run a
board with it, and it's causing problems.  I can dial out with
no problems.  I dial out and connect to just about every board at
high speed on the first shot.  But, it does NOT take very kindly
to when users call my board.  Below is a list of some of the
strange things it does:

1. For some, not all, 2400 baud callers, it sends the file much
   too fast, causing the receiver to not be able to keep up,
   thus the download aborts.  I notice that it takes off too
   fast (a normal Zmodem download), and has sent so many bytes
   so fast that they just can't keep up.

2. Some users are getting periodic line noise out of nowhere, ever
   since I installed it.

3. Certain users have trouble uploading, too many errors.

4. It is VERY picky about who it lets connect to me at high speed.
   It seems that it will only let a Dual Standard connect really
   correctly.  I've had 9600 and 14400 Dual Standard callers call
   in and connect the first time, error free, and the transfers
   and everything are perfect.  However, it doesn't seem to like
   other types of high speed modems.  A friend of mine just bought
   a Zoom 14.4 V.32bis, and when, after calling other high speed
   boards and connecting no problem, he tried to call my board, it
   just wouldn't go.  My modem picked up, started to connect, then
   stopped, tried again, stopped, tried again, etc. until it timed
   out.  The same thing happened with a user who has a Hayes Smart-
   modem 9600 V.32.  He calls in and it just refuses to connect,
   just a lot of screaming.  He had to drop down to 2400 to connect.
   This shouldn't be.

5. On a few boards that I do try to dial out to, I can't connect.  Now
   99% of the boards that I call out to I connect beautifully, but
   that's not the case with the Secret Service BBS in Hunnington,
   West Virginia.  The high speed handshake just goes on FOREVER,
   and eventually it times out.  And when I try to call HAL 9600
   (they run 14400 ironically) I usually connect at 12000 and then
   get disconnected.

6. During transfers with some people (ONLY through the BBS, never
   when I'm logged in to a board, keep in mind all of these problems
   happen through the BBS only for the most part), it sends 1024
   bytes, then 2048 bytes, then 3072 bytes, then a few more.
   After that, it goes back down to 1024 again!  Goes up to 2048,
   then goes back to 1024 once again!  This is very upestting to me.

It's just very frustrating.  I don't want to think that I got a
bum deal.  The Intel 14.4 EX was rated VERY highly in PC Computing's
June top products issue, and also excellently in other reviews, right
up there with the USR.  So, either I got a bad one or I'm doing
something wrong.  My initialization string for when I dial out is
ATZ^M, and my initialization string for the BBS (actually FrontDoor)
is ATZS0=0E0M0H0&D2^M.  My error correct message is REL, and I
have the serial port locked at 38400 baud.  (It can handle 57600 but
some doors can't)  Also, on the BBS, it draws on my end at 38400
baud, so if a user tries to spacebar abort a menu or screen, they
have to be VERY quick, because if they even wait a second the whole
thing is already drawn on my end and in the buffer, so there's
nothing to space.  I run TriBBS 3.3 and love it.  I doubt the board
has anything to do with it, could all of this be caused by my
string possibly being off?  Also, I don't have a high speed serial
card, I use the same serial card that came with my computer, which
came with an internal 2400 modem.  Might a newer, faster serial
card help?  If so, what should I get?

Can anybody help?  PLEASE!!!  Thank you in advance.
