HELP!  I have an Apple Super Serial card that I'm trying to use with an
external modem.  My system consists of a //e with extended 80-column
card, the super serial card, and a parallel printer interface.

When I put the Super Serial into dumb terminal mode, two things happen:

1. With nothing connected to the D25 connector, and local echo enabled,
all appears well in 40-column mode.  But if the Super serial is put into
dumb tty mode using 80-col. mode, the cursor always remains in column 2
of the current active line.  Aside from this, all else seems normal --
but with no cable attached.

2. After entering dumb tty mode (and verifying it using local echo), I
connected the modem (VADIC 34xx, VA212, US Robotics -- doesn't make any
difference) using a "standard" cable.  I've been using said cable with
my dumb terminal and no problems, so I don't suspect the cable -- I can
loop back TXD to RXD without connecting DSR or DTR and actually echo to
the screen of the //e.  But connect a modem (who will assert DSR), and 
the Apple is now a very dumb terminal!  It does assert DTR, but will not
respond to keyboard input -- my last test involved using the modems
loopback capability, so anything sent should have been echoed.

Questions:

	1. Has anyone seen this problem?
	2. Has anyone used a Super Serial successfully with a //e?
	3. Is DSR killing me?  If so, WHY?

So far all I've gotten from my dealer is a $25 bill for "Warrantee
service -- No problem found"(!), and "it's probably your configuration".
Since my box was purchased as a complete system, I've got to thinking --
Do they run diagnostics on these things?  Doesn't "configured for use
with modem" mean configured for use with a modem?

PLEASE, if you have any solid information -- send it my way!  At the
moment I suspect that I'm going to run into the "Well, we found a
problem -- but you're 2 days out of warrantee" syndrome.  Grrrr.
(Sorry about the editorial comments, but if net-people won't listen,
who will?)
