Do I need to initialise the 80col card in some other way? TEXT:HOME
perhaps?
Line 10 tells the system to redirect output to the 80 col init routine
Line 20 tells the system to redirect input from the serial card init
routine
Line 30 calls the serial card init routine and returns when a
character arrives
Line 40 sends a character to the 80 col init routine which finally
switches from 40 to 80 col mode AND installs the 80 col input handler
overwriting line 20's effect..
You need to do some output between line 10 and 20. eg:
15 PRINT
Thank you, that is now very close to working.
The only real issue I have now is that when in 80col mode, there's no
cursor but there is a white block with a ` in it in the second col. And
it persists there. Typing tracks left to right, starting one to the left
of this block, then overwriting it with the correct (but reverse videod)
letter, then continuing on normally. Oddly, numbers typed in that column
get corrupted, so starting a new line and typing '123456' (without the
quotes) gives '1r3456' with the 'r' being reverse-videod, but typing 'hi
there' gives you 'hi there' but with the 'i' reversed.
Any idea what that would be? I'm using 9600 8N1 as the comms settings
for now.
