I am getting the blue screen with IRQL_NOT_LESS_OR_EQUAL but only when I run a communications utility within my application (a custom vb2005 and C++ graphics manipulation program). The communications feature uses an RS232 connection to a similar program on another computer to exchange information. Lower down the blue screen it says:
*** stop: 0x0000000A (0x0000BA33,0x00000002,0x00000001,0x806E6A8E)
The computers are Winows XP, SP3.
We currently use the motherboard RS232. I'll try an adaptor. Any other suggestions?
