All right, I'm getting warmer. I tried changing ttys to various speeds, 
and stty 9600, per Clem, Then, I looked at termcap, and saw that there 
weren't any ansi or vt100 entries (duh), so then I tryed vt50 and vt52 
modes:

vt50:

       ~
       AAAA




           :q

vt52:

             ~Y, Y7 :q


Here are the termcap entries. I compared with termcap in svr2, which has 
vt50,vt52, and vt100:

Here's the list of available terminals culled from /etc/termcap from v7 
and the buggy/untested list included in termcap:

    dumb, lsi adm3/adm3a/adm31/adm3a, concept100/concept100rv, hp2645,
    dm1520/dm2500/dm3025/3025a, dec gt40/gt42/vt50/vt50h/vt52, decwriter
    I/decwriter II, diablo 300s, hazeltine 1500/1510/2000, Infoton
    100/400/KAS, fox 1100, owl 1200, tektronix 4014, teleray 1061,
    terminet 1200/300, tty33/37/43, ti silent 700/745, xitex sct-100,
    beehiveIIIm, tvi912/tvi920, ttyWilliams, infoton|400|infoton 400

    buggy -dm2500
    Untested - gt40, gt42, vt50, vt50h, dw1, dtc300s, gsi, infoton, fox,
    tk4014, t1061, 1200, 300, tty33, tty37, tty43

I don't suppose any of these look like reasonable approximations of 
something I have available in Terminal/xterm?
