 gpib - Generic GPIB Record
The GPIB record is designed to perform generic GPIB I/O. It is intended to allow EPICS to communicate with a new GPIB instrument without even rebooting the IOC, i.e.
GPIB Universal Commands are commands which are directed to all devices on the GPIB bus, not just addressed devices.
GPIB Addressed Commands are commands which are directed to only the addressed devices on the GPIB bus.

 CSD - March, 1998 - Using GPIB Instruments to Test Communication Systems
The data rate over the GPIB bus (1 Mbps maximum) is substantially influenced by the specific instruments used on the bus, the physical cable lengths between instruments, and the number of devices powered on the bus.
The instruments connected to the GPIB bus are configured (at the instrument) as talkers, listeners, or both, depending on the function of the particular instrument.
The ideal GPIB test configuration would be physically connected so that all GPIB devices are powered on, all GPIB cable lengths are as short as possible, and all GPIB devices are spaced equally on the order of one device every meter of cable length.

 Gpib device and driver support
GPIB devices typically have many parameters, each of which may be thought of in terms of the standard types of database records available in EPICS.
The GPIB library compares this pointer's value to that of the record's DSET field to assure that the user specified parameter is valid for the record type being initialized.
The GPIB device support library currently supports devices like these by providing a flag in the parm block that can be set to a non-negative value indicating that the library should read data from the device on every type of operation defined in the parameter table.

 The GPIB FAQ 1.0
Although the GPIB interface is in fact a fairly general purpose bus, its primary use is to connect one or more GPIB-compatible instruments to a PC, and several thousand such GPIB products are available on the market.
In a GPIB system, however, there can be more than one listener and the three-wire system prevents multiple acceptance of data by a fast listener while a slow one is still busy accepting the data.
To initialize a GPIB system, the first thing the controller typically does is to send the Interface Clear (IFC) command by asserting the IFC line for a few hundred microseconds on the GPIB bus.
