Serial Communications

["tolsen64" <tolsen64@hotmail.com>]

Does the GS just dump characters if the incoming text is too fast?  Or
can that even happen?

Here's what I have:

GS -> Ethernet Modem -> Internet.

When I telnet out to a server (NNTP or SMTP), I lose half the
characters in the response, so what i'm getting back is useless.

Both the GS and the Ethernet Modem's serial speed is set to 19200.

I thought it might be handshaking so I spent the day studying every "GS
Handshaking" article I could fine (there are a lot of different
versions of the beast).  All of them go from the MINI DIN-8 to DB-25.
My Ethernet Modem has a DB-9 connector so I tried to "adapt" by
cross-referencing the DB-25 signal names to the same on the DB-9.  But
I couldn't get it to work (I couldn't transfer data at all) whichever
cable i built.

The cable I have working now works great as long as i'm not receiving
more than a few characters at a shot.  The BBS currently runs using
this cable.  I got this cable working by trial and error and I'd have
to ohm it out to tell you what it's pin-to-pin connections actually
are.  But it evidently doesn't handshake.

The other cable I have is one that I used when I had the GS hooked up
through the PC to the internet.  It always worked fine.  I got
everything that was coming in (I had internet email working on my bbs).
 But that cable doesn't work with the Ethernet Modem.

I'm wondering if the Ethernet Modem is just too-darn-fast for the GS.
I've tried turning on the Buffering & FIFO options in the Ethernet
Modem to no avail.  If I turn on the DTR Handshaking in the Ethernet
Modem, I get no communications at all.  It only works if I set it to No
Handshaking or Xon/Xoff.  But I still have the problem of losing data
when a bunch comes in.

It seems as if I have hit a brick wall here...
