#include <stdio.h>
int ieeedata,ieeectrl;
char buffer[255];
void main(){
ieeedata=open("IEEEDATA",O_RDWR);
ieeectrl=open("IEEECTRL",O_RDWR);

IEEE Bus Commands And Functions.

ABORT Resets bus, pulse IFC, assert REN, assert ATN.
BASE= Sets the PC IEEE board base i/o address.
CLEAR Returns some or all devices to predetermined state.
CONFIGURE Specifies how device responds to PPOLL.
DISABLE Prevents some or all devices responding to PPOLL.
END= Sets End of Sequence method for OUTPUTs.
ENTER Ask for data from IEEE device.
EOS= Specifies EOS byte for IEEE data INPUTs to PC.
INIT Restores IEEE bus and driver to defaults state.
LOCAL Enable front panel control. REN, ATN sent false.
LOCKOUT Disable front panel controls. Performs LLO.
NO TO Disables time out.
OUTPUT Sends literal data string to addressed devices.
PPOLL Performs a complete Parallel Poll
READ Reads one byte of data from addressed talker.
REMOTE Puts some or all devices under PSI BOX control.
SLAVE Puts PC into peripheral mode.
SPOLL Serially Polls one or more devices.
STRING Sends literal data string to current bus device.
TO Sets an i/o timeout value.
TRIGGER Initiates pre programmed action in devices.
UNCONFIGURE Prevents devices responding to Parallel Poll.
WAIT SRQ Waits till SRQ is asserted by device.
WAIT MLA Waits till PC is addressed to listen.
WAIT MTA Waits till PC is addressed to talk.
NO ATN Set ATN false.
NO REN Set REN false.
LISTEN Sends one or more Listen Addresses.
ATN Asserts ATN line true.
