When the host has sent enough data for the moment, ATN line is set to true and " Device number 8, unlisten " is sent.
12.
Device numbers may be combined if the device provides multiple functions, such as the instantaneous / time-delay AC over current relay denoted as 50 / 51.
13.
The canonical list of these prefixes can be found in the Linux Device List, the official registry of allocated device numbers and / dev directory nodes for the Linux operating system.
14.
On higher logical level the host will set the ATN line to true and transmit the bytes " Device number 8, listen ", " Secondary address 2, open ".
15.
Over the years many programs assumed that there is only device 8 and do not allow selecting anything else; this can be worked around by temporary changing the used IDEDOS device number to 8.
16.
Often, the last two digits of the device number are the output voltage ( e . g ., a 7805 is a + 5 V regulator, while a 7915 is a " 15 V regulator ).
17.
"IN " and " OUT " tokens contain a seven-bit device number and four-bit function number ( for multifunction devices ) and command the device to transmit DATAx packets, or receive the following DATAx packets, respectively.

The limitations of BASIC 2.0 on the C64 led to use of built-in ROM machine language from BASIC . To load a file to a designated memory location, the filename, drive, and device number would be read by a call:
19.
However, device numbers do not reveal any similarity between different type families; e . g . the triode section of an ECL82 is not related to either triode of an ECC82, whereas the triode section of an ECL86 does happen to be similar to those of an ECC83.
20.
BASIC 7.0 includes DLOAD and DSAVE commands to support loading and saving to disk without using the, 8 or other device number, and also a DIRECTORY command that reads a disk's catalog information directly to screen memory without overwriting BASIC memory as in BASIC 2.0.
