3.2.1.2 Terminators

The following conventions apply to terminators:

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

the transfer of a character, EOI signals that character as the

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

be asserted during transmission of the last character
