term

Any single character, specified as CR, LF, 'X', as described

previously; part of terminator sequence used to mark the

end of lines of data and commands.

EOI

The IEEE bus End-Or-Identify signal; when asserted during

input to stop. On output, EOI causes the bus EOI signal to

be asserted during transmission of the last character
