AEX If input conditions are true, the controller extracts 10
characters starting at the 42nd character of ST38:40 and
store the result in ST52:75.
Convert Integer to
ASCII String
AIC

Status Bits:
EN-Enable
DN-Done Bit
ER-Error Bit
If input conditions go from false-to-true, the controller uses
the AND and OR masks to determine whether to set or
reset the DTR (bit 0) and RTS (bit 1) lines, or leave them
unchanged. Bit 0 and 1 of the AND mask cause the line(s) to
reset if 1 and leave the line(s) unchanged if 0. BIt 0 and 1 of
the OR mask cause the line(s) to set if 1 and leave the
line(s) unchanged if 0.
See page F-8 for a description of prescan operation for this
instruction.

EM - Empty
EU - Queue
If input conditions go from false-to-true, read 50 characters
from the buffer and move them to ST52:76. The number of
characters read is stored in R6:32.POS and displayed in the
Characters Read Field of the instruction display.

If input conditions go from false-to-true, read 18 characters
(or until end-of-line) from the buffer and move them to
ST50:72. The number of characters read is stored in
R6:30.POS and displayed in the Characters Read Field of the
instruction display.
