The MARKDRVR command is then followed by the commands needed to install the TSR programs.
When using Driver488, these would be the DRVR488 commands. When these commands have
completed, Driver488 is installed and ready for use.
When Driver488 is no longer needed, it can be removed by using the REMDRVR command:
C:> REMDRVR
REMDRVR prints out the comment that was saved by MARKDRVR and then uses the information that
MARKDRVR saved to restore the system to the state it had before MARKDRVR had been executed. This
removes Driver488 and any other TSR programs that had been loaded in the interim and recovers their
memory for reuse.
If several different TSR programs are being used, then it might be appropriate to use MARKDRVR more
than once. Then, when REMDRVR is used, it will only remove the TSR programs that were installed
after the last MARKDRVR command. Each time REMDRVR is used, it will remove one more “layer” of
TSR programs. The comment saved by MARKDRVR can help keep track of which TSR programs are
removed at each step.
Note that the most recently installed programs are always removed first. It is not possible to remove a
program until all the more recently installed programs have been removed.
When working with Power488, it is good practice to create a DRIVER.BAT file that includes the
DRVR488 commands as described above. Then a MARKDRVR command, such as MARKDRVR
Driver488 can be added to the beginning of the DRIVER.BAT file. Then, Driver488 can be installed
by typing DRIVER and removed by typing REMDRVR . Driver488 can thus be installed and removed as
desired, without rebooting the computer.
Moving Files from an IEEE 488 (HP-IB) Controller to a PC
Included on the Driver488 release disk is a utility program that allows files to be transferred from any
IEEE controller to the PC in which Driver488 resides. This utility program configures the PC as a
Peripheral on the IEEE network, much like a standard IEEE 488 printer. Any controller capable of
sending information to an IEEE 488 printer, including controllers like the HP 9000 series computers,
can send any type of data to the PC.
Once launched to the PC, the file transfer utility allows the operator to redirect the incoming data either
to the PC screen, a PC disk file, or a printer attached to the PC.
PRNTEMUL Files
In the \UTILS subdirectory of the Driver488 diskette, there are 2 files:
•
PRNTEMUL.EXE : This file is the MS-DOS executable version of the program. This is all that you
will need to emulate an IEEE 488 printer on a PC/AT or PS/2 computer.
•
PRNTEMUL.C : This is the C source code of the PRNTEMUL.EXE program. It uses a C subroutine
interface of Driver488, which is located in the \SUBAPI directory of the main Driver488 directory.
Refer to the corresponding language support section on how to compile this code.
Configuration of the IEEE Interface for PRNTEMUL
The PRNTEMUL program requires the Driver488 to be configured as a Peripheral (same as an IEEE
printer). Make sure that the IEEE interface is configured at a unique IEEE address.
Once Driver488 is configured properly, reboot the computer and connect your PC/AT to your IEEE
controller.
Running PRNTEMUL
After the IEEE interfaces of each computer has been configured and connected, run the PRNTEMUL
program from the \UTILS directory by typing one of the following commands at the DOS prompt:
