GPIB-RS232 lock up in c-mode

[davidipos]

I have a simple driver talking to a GPIB device in c-mode.

This is working.

I am testing what happens in fault conditions.

If I power down the GPIB device and send a character on the RS232 I get the the following LED pattern:

RDY - Red

LSTN Green

ATN Yellow

FULL Yellow

BUSY Yellow

The only way out of this condition is to cycle the power on the GPIB-RS232

How do I make my application more robust?

I ran into the same problem.

C-mode is not robust.

You have to change it to S-mode and program in S-mode to prevent it from locking up.

Its a pain since S-mode is more complicated and has it's own special syntax but its the only way I've found around it and it doesn't lock-up.
