I am having problems with the initialization of the GPIB hardware using the NI driver modified for QNX. I experience one of 2 problems:
1) The initialization fails in the nitn_presence_check() where a check is made on adr1 and sts2.
2) If the presence check passes, then I get the driver looping in the nitn_wrtPIO() at the lines where the "wait for ENOL" is performed.
Any ideas why this might be happening?
