<Wrong... (I think). My memory may be hazy but...
<The VT132 (and 131 I believe) both were capable of block mode.
<The 132 (I thought) was a 102 with block mode, AVO and Printer port
<capability.

Might be right, though I thought that was the VT161/2. there were a lot
of "flavors" of those.

<The VT131 had Block mode, STP, AVO done the old way... All three
<options and different roms.
<
<The 132 was a cost reduced 131 based on the 102 which came standard
<with 24 lines of 132 (without AVO) -- It was built in the standard
<VT102 logic board.

Thats it.

<The VT101 was a 102 without the AVO memory (I think) and was the bottom
<of the line VT10x in cost.

Yep!

<I think the 102 and 132 allows hardware flow control like the VT220.

Actually they all did. it was called restraint mode (pin 19 or 21)
I'd have to look).

<There were some interesting illegal (and legal) escape codes that did
<interesting different bugs to the VT100, 101 and 102 based on their
<setup settings. One of these bugs caused hell for VT102 and 101 users
<when the EDT program slowed their scrolling down to a crawl back around
<VMS 3.2 or so.

Ah yep. Remember the fix, VT52mode. Then came the group that produced
the Video SRM and later the printers SRMs (DEC STDs). the goal was to not
break anything and have compatability that made sense for later products.
