 According to the documentation EK-M9312-TM-002 M9312
 Bootstrap-Terminator Module Technical Manual
 there are two addresses to use for the Console Emulator.
 165020 (765020)  for Console with Diagnostics  SW 1 and 7 on
 165144 (765144)  for Console w/o Diagnostics   SW 1,5,6,9 on
 The switch settings below correspond to xxx004.. which is probably the
 first drive for the ROM in position 1 and does
 not invoke diagnostics.
 Have you tried 173000 (773000)?

 I have bi-directional communication from PC/Hyperterminal.   I forgot
 about having to tell HyperTerminal to echo characters locally. Anyway, 'a'
 comes over as 000141 and 'A' comes over as 000101. So far so good.
 However, I have not gotten "@"

 Any suggestions?  I have other M9312s I could try.
