It don't think it would help too much with the IIe firmware 80-column scrolling that will lock out interrupts. Now if you're talking about making a big buffer simply to capture everything that's been sent in to the SSC, then yes I would agree that would be a good idea, but not in the IRQ routine as I currently have it designed. > and what is received through the SSC card > is only printed to screen and not saved to a disk file. I was thinking about adding a Control-P command to route input to a printer. Then there could be a Control-D to save to disk. > > Any chance for an update :) > Yes, because I want to add slot independence, and I think some more of these other suggestions too. -- ]DF$ Apple II Book: http://macgui.com/newa2guide/ Usenet: http://macgui.com/usenet/ <-- get posts by email!
