3.2.1.1 Bus Addressing

The following conventions apply to bus addressing:

addr

An IEEE bus address in the range from 00 through 30.

cmd$

An arbitrary command string which is sent to the
particular IEEE device being addressed.

CR

The carriage return character ($13, $&H0D).

LF

The line feed character ($10, $&H0A).

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
last in the transfer. On input, EOI, if specified, causes the
input to stop. On output, EOI causes the bus EOI signal to
be asserted during transmission of the last character
transferred.
