My news is more a question than a news item. I have been working with a TRS-80 Model III micro trying to mask out certain interrupts thru the hardware. According to documentation available, a reset bit in port E0 will deselect a certain interrupt. I have chosen to inhibit the RS-232 xmit buffer empty interrupt. The program I am writing will keep track of all system interrupts and still sees this type of interrput with it deselected. This is supposed to be turned off by clearing bit 4 in port E0. Clearly it is not. Any information on this type of problem ??
