GPIBENET100_RevB7 firmware revision addresses the following issues: -When using LabVIEW to do GPIB I/O, an error occurred with transfer sizes greater than 16 KB. The final count reported after the I/O completed was not correct. -When making the first ibsgnl call to the GPIB-ENET/100 with a non-zero mask the function worked, but incorrect status was returned. -When a signal was raised due to a GPIB event, the signal handler would have to issue another ibsgnl to rearm the signal. This is incorrect, because signals (once armed) should automatically rearm upon signaling. See the Getting Started Manual for your GPIB-ENET/100 for more information on updating the firmware.
