Hi Henrick;
This forum is great!
Thanks a lot for your intervention!
With:
DEFINE OSC 16
DEFINE CHAR_PACING 500
Symbol BAUD = N2400

The three pulse bursts are well separated by 0.92msec and the display responds well.
What is the relationship between parameter 500 and the 0.92msec timing?
Why not 500µsec?

Testing:
If I test with DEFINE CHAR_PACING 1000, the difference is 1.4 msec and the display is a bit slower.
On the other hand, with DEFINE CHAR_PACING 250, the gap between the bursts is 0,64msec and the display does not work anymore.
