Hi... I'm having a large problem interpreting Apple's documentation for the COMMAND register of the SSC ($C08A). Especially the low nibble. The only documentation on setting the interrupts is on page 54, and it says next to nothing about them. If anyone can guide me to the correct explanation of this register, I'd be very happy. A little background on my problem: I have written a driver for a BBS, and found out that at certain times when I lose carrier, instead of behaving properly and going to the right line number, TRACE gets turned on, and ProDOS gets disconnected. I have narrowed it down to a problem with the DTR. Now I just have to find out WHAT this problem is. (I'm using an Apple 2e, enhanced, with a Hayes compatible modem -- AT&T 4024). So...anyone out there that can help me out? Thanks... Rob robert_l_heiser@cup.portal.com
