Ok, good news... I found the issue that was reported with the 64 door. It seems that using 9600 baud just so happens to catch a race condition that the code has had for 2 years. I run at 57600 baud with the WiModem232 and 2400 or 38400 baud with the WiModem for the C64, so I have never seen the issue before.
I am going to have to re-write the entire receive portion of the code to correct this. But, it will definitely fix the issue. I received more displays today, but I am not going to allow more orders until this is resolved. Perhaps a day or two.
