Dial-out/in now works just peachy on my machine.
The biggest help to me was:

Simply deleting /dev/ttya allowed my configuration to work.
Wonderful suggestions for debugging were:

A hint about 'tip' would seem to agree with my experience:

> RING status values, all of which abort the connection. Also, I had to

My thanks go to those who responded:

The only thing that still doesn't work is SunOS 'tip', but SunOS 'cu'
works and 'tipx' (version 1.21) works.
Below is the setup that rendered a working dial-in/out.
1. Device ownerships and permissions.
crw------- 1 uucp uucp 12, 128 Apr 17 00:40 /dev/cua0
crw--w--w- 1 root wheel 12, 0 Apr 17 00:33 /dev/ttyd0
2. The modem cable must pass the carrier detect line.
3. /etc/ttytab needs the following reference. Note that references to
ttya and cua0 are gone.
::::::::::::::
/etc/ttytab (partial)
::::::::::::::
#
# name getty type status comments
#
ttyd0 "/usr/etc/getty D2400" dialup on modem
NOTE: A couple people commented that my posting had "local" in place of
"modem" above. That was due to clerical error on my part for
having cut-and-pasted together the pieces of my message after I
put things back to "semi-working". I had tried a non-local field,
but without success originally.
4. I explicitly turned off soft carrier on ttyd0 since ttysoftcar -a never
worked for me. Building a new kernel is not necessary.
::::::::::::::
/etc/rc (partial)
::::::::::::::
/usr/etc/ttysoftcar -n ttyd0 > /dev/null 2>&1
5. Set up the UUCP/cu Dialers file to reflect the desired modem
initialization:
::::::::::::::
/etc/uucp/Dialers (Partial)
::::::::::::::
# Avatex 2400 (Hayes compatible)
hayes =,-, "" \dA\pT\pE0\pV1\pM0\pL0\pX2\pQ0\pS0=2\pS2=255\p
# THIS LINE ISN'T REALLY BROKEN -- I BROKE IT FOR THIS POSTING
S12=255\p&C1\p&D3\p&W0\r\c OK\r \dATDT\T\r\c CONNECT
6. The ACU is /dev/cua0 in /etc/uucp/Devices and /etc/remote.
::::::::::::::
/etc/uucp/Devices (Partial)
::::::::::::::
ACU cua0 - 2400 hayes
ACU cua0 - 1200 hayes
ACU cua0 - 300 hayes
::::::::::::::
/etc/remote (Partial)
::::::::::::::
