There is no problem saving and loading files with vic-20 and 1581,
but the chrout return value always indicates a timeout when sending
data from vic-20 to 1581, although the data is correctly transmitted.
I think I first noticed this with the machine language monitor module,
which fails to save memory areas (it does not use SAVE, at least I
think I checked that it used chrout or the serial bus routines).
The next time I came across this when I adapted the Veni Vidi Vic!
loader to 1581: sending the drive code failed if I checked the
chrout return value...
So, the sad thing is that programs that perform error checking
fail, while all that omit error checking work just fine..
