Connecting a modem on a 2100 standalone

I've gone back through the summaries on this group and tried to apply the
suggested actions for modems and Alphas, but still no success. I am trying
to
attach a 28.8 modem off of the back of an Alpha cabinet to COM2 (the top COM

port according to the Owner's Guide p.1-35). The Alpha is running DU 3.2C
and
the modem is a Best Data 28.8 (I've also tried a USRobotics Sportster 28.8
right
out of the box).

  I've mv'd /dev/tty00 and /dev/tty01 to /dev/ttyd0 and /dev/ttyd1. The
file
results are:

   /dev/ttyd0: character special (35/0) ACE_SLU #0 terminal #0 modem_control
off
   /dev/ttyd1: character special (35/1) ACE_SLU #0 terminal #1 modem_control
on

Here are the relevant lines in the various files:

/etc/inittab:
   u1:23:respawn:/usr/sbin/getty -h ttyd1 M19200 vt100

(I was trying -h to see if it would hold on to the line. See the tip
attempt
below. I've also tried uugetty.)

/etc/gettydefs:
    19200# B19200 HUPCL CS8 CLOCAL # B19200 SANE IXANY TAB3 CLOCAL #login:
#9600

    M19200# B19200 HUPCL CS8 # B19200 SANE IXANY TAB3 HUPCL #login: #M9600

    38400# B38400 HUPCL CS8 CLOCAL # B38400 SANE IXANY TAB3 CLOCAL #login:
#19200

    M38400# B38400 HUPCL CS8 # B38400 SANE IXANY TAB3 HUPCL #login: #M19200

    7bit.19200# B19200 HUPCL CS7 CLOCAL # B19200 SANE PARENB CS7 ISTRIP
IXANY
TAB3 CLOCAL #login: #7bit.9600

    7bit.M19200# B19200 HUPCL CS7 # B19200 SANE PARENB CS7 ISTRIP IXANY TAB3

HUPCL #login: #7bit.M9600

    7bit.38400# B38400 HUPCL CS7 CLOCAL # B38400 SANE PARENB CS7 ISTRIP
IXANY
TAB3 CLOCAL #login: #7bit.19200

    7bit.M38400# B38400 HUPCL CS7 # B38400 SANE PARENB CS7 ISTRIP IXANY TAB3

HUPCL #login: #7bit.M19200

/etc/remote
        modem:dv=/dev/ttyd1:br#19200:pa=none:

This is currently what is happening:

        # tip modem
        connected

        Lost carrier.
        [EOT]
        #

So, I tried commenting the getty out of the inittab to see if I could reach
the
modem directly. This time, when I tried "tip modem" and tried to enter any
characters, it hung on me.

Curious, though, the Best Data 28.8 when plugged in, shows the TR light,
while
the USR Sportster shows the CS light.

Any hints?
