- Flashing text is one of the few things, that the peecee's can easily create
- due to their text-mapped display.
-
- On the Amiga, however, the display is bitmapped, so reproducing flashing
- text would demand a routine to constantly swap colors between the
- background color and the foreground color.
-
- For a single character in an 8x8 font like topaz 8 or jrcibm 8 this is not
- really a problem, but imagine a 640x256 display that has to be flashed.
- It's 32 lines with 80 characters each line. This amounts to 2560
- characters.
-
- If we got an 8 color display, this is 3 bitplanes and so it is 2560 x 8 x 3
- bytes = 61440 bytes, that would have to be swapped.
-
- With a flash period of 1/2 a second, this would mean, that 122880 bytes
- would have to be changed each and every second. And you would have to
- support 4 bitplanes, i.e. 16 colors, as well... Phew!
-
- If you're doing it another way, swapping displays, it would mean, that you
- would have to update two displays when you receive a single character on
- the serial port. This would probably be a little faster, but still, you
- can't really do it and still get reasonable speed out of JR-Comm...
-
- I have tried to do a workaround on this myself, as I have written a
- commercially sold terminal software package, but with the options given
- from a bitmapped console, it's not that easy to make it fast, I can tell
- you...
-
- I'd for sure rather be working with a FAAAST comms program and miss the
- flashing text, than look at one, that has flashing text and is a speed-pain
- in the b*tt...
