Hallo Pasi,

> Can't you just start the transmission then? 

This is the sequence of bytes.
$3F  $28  $F0  $24  $3F    $48  $60    $01  $04 . 
               "$"              Talk   Address

Only after receiving $60 I know I'm supposed to send a file. In the above
sample the filename is "$" meaning that the 8032 doesn't want to load a file
but the directory. 
Then my PC has to search the directory of the D64-file to see if the file is
present. The last action preceeding the transmission of the address is
loading the first sector in memory. Only then I can start sending the data .
But probably these actions take more time then I'm allowed :( FYI, the
program runs on a laptop with a Celeron 400 MHz.

As said in an earlier email, when asking for the directory I noticed that
the drive already started running after $3F and that's how I solved my
problem: reading the directory and storing it in memory.
But to be honest I simply forgot to observe at what point the drive starts
running when asking it for a file.
