The DEVICE File (#3.5) is stored in the global root of ^%ZIS(1, and each entry corresponds to a name for I/O (Input and Output) in the VistA system. Generally speaking characters are sent to and received from an I/O device in most computer systems as a normal part of interaction with a user.

The devices in VistA are segmented by the TYPE Field which has the following values:

INTERNAL ABBREVIATION EXTERNAL VALUE Intended use
TRM TERMINAL hard connected terminals such as consoles
OTH OTHER
MT MAGTAPE sequential magnetic tape
SDP SDP unused- was Sequential Disk Processing - MUMPS-as-OS disk storage
SPL SPOOL unused - was in-MUMPS disk/printer spooling
BAR BARCODE READER
HFS HOST FILE SERVER commonly used - filesystem storage, print spooling, etc.
VTRM VIRTUAL TERMINAL soft connect terminals over the network
HG HUNT GROUP providing for banks of "alike" devices
RES RESOURCES synchronization and limiting background processes
CHAN NETWORK CHANNEL devices attached with TCP/IP addresses and ports
IMPC IMAGING WORK STATION
