Hahahaha, reminds me of a conveyor project I did once. The system was supposed to support 2 transactions a second and communicate them to a DEC VAX via a software package of theirs called PAMS. They claimed it was as reliable as the mail in communications.

At first they wanted the network card in my sort controller but I refused because my system was heavily interrupt driven and I had another computer specified that my program would send the transaction to through RS-232 communications and from that computer into the VAX via their interface card.

Best decision I ever made. Even though they knew the transactions were going to come in at 2 per second, their interface protocol would take 15 seconds (per transaction!) to determine if the VAX was down before they would store the transaction locally and then return control to my communications software. They disabled interrupts during that time so I couldn't use interrupts to receive my transactions, but had to resort to using the Clear To Send pin to mediate communication between my sort controller and the communications computer. It was even more hilarious when communications with the VAX was reestablished and their software seized control once again until all the backed up transactions had been transmitted. Should I be cruel and mention they did not dynamically allocate disk buffer space for the locally saved transactions but instead predefined the buffer size and locked up when it became full?

Of course DEC was not going to take the blame, instead of sending a programmer to meetings with the client, they sent a lawyer. I finally said I was willing to throw down printouts of my code for them to crawl over and tell me where I had gone wrong. Were they willing to do the same? They finally conceded that there might be a problem with their interface card.

It would have been far less of a hassle if they had let me write the communications protocol to the VAX as well, but hey, I was not an employee of the All and Powerful Digital Equipment Corporation, so what did I know?
