Re: [Linux-gpib-general] I need some help debugging an ECIC problem with my card

[dave p. <dpe...@gm...>]

Hi David,
Thanks for the good news. The cable or some device on the bus was asserting
ATN:
With the cable plugged in:
Initilisation        ibsta 0x1110 lines 0x72ff ibsta 0x1110 <-- ATN | SRQ |
REN | NDAC
So correctly the board did not transition to CIC because it saw someone
else on the bus was CIC.
With the cable unplugged ATN is not asserted:
Initilisation        ibsta 0x1120 lines 0x30ff ibsta 0x1120 <-- SRQ | REN
Mystery solved.
cheers,
-Dave
