MAX communication hangs after Standby Mode(with GPIB PCMCIA)

I have a IBM Laptop with MAX 2.2 and a GPIB PCMCIA Card installed. After booting the computer I can communicate with GPIB instruments without problems. After I get the Laptop out of a Standby Mode, MAX can not make any connection to GPIB devices; when I scan for Instruments it hangs as well.
The troubleshooting wizard tells me: one or more GPIB interfaces failed.
Does anyone have the same problems or solutions ?

Hello-

It's best not let the computer go into standby while applications are using hardware. http://www.freevbcode.com/ShowCode.Asp?ID=2596 talks about this problem with network cards from different vendors. The link also includes an example program that prevents standby.

i have same problem with PCMCIA GPIB
it used to recover from suspend on win98 ok as long as there was no GPIB activity (HP Omnibook XE3).
now with win 2k (on an Omnibook 6000) it just locks up. you have to restart the machine to get the GPIB to work again, i supose the whole system does not lock so things could be worse.
is there a patch ??

On the NI-488.2 2.0 download page it is mentioned that that driver does not support standby mode. No such mention is made on the download page for NI-488.2 version 1.7 (which I need to use for my PCMCIA-GPIB interface), although the 1.7 release shows very much the same problem: After stand-by, communication with the GPIB port is no longer possible.

The Visual Basic example tool for preventing stand-by may help those users who are familiar with VB, but it does not help me.
Frankly - what I'd like to see is an improved NI-488.2 version that does support stand-by. Does NI consider providing such an upgrade/patch?
