[comp.sys.apple] TIC and Interrupts

delton@pro-carolina.cts.COM (Don Elton) (01/13/88)

You said that when you didn't have interrupts enabled on your serial card that
you lost a few characters and that when you had them enabled you lost all
characters....

In point of fact, you had the switch settings reversed.  TIC won't work at all
without interrupts enabled.  Sounds like you were losing data because you have
an unenhanced //e.  If you get the //e enhancement kit you get new ROM's that
fix a design error whereby the //e turns off interrupts for a long time during
screen scrolls.  TIC won't lose data at all if you have the enhancement kit
(or a recent //e or a //c or a IIgs of course).  There is no non-interrupt
mode available in TIC.
