Hi Ruud, this is not a matter of being fast enough, but a matter of where to actually read the data. If I remember correctly, I had quite some pains with my IEEE488 implementations until I (think I) decided to simply read the data during the open, when the drive receives the UNLISTEN (from open, and maybe even during UNTALK from the previous read). The the PET would wait with the open until the data is available and would not time out when it sends the TALK. (But that is from my memory only, so take it with a grain of salt).
