Hallo Andre, > But I cannot see that when the actual command is send [*], Reading this I don't even understand myself. I meant to say: At the moment TALK is received, I have no means to see whether the contents of the directory is requested by means of 'DIRECTORY' or 'LOAD "$",x'. And thus the delay is inserted, whether it is needed or not. > I still wonder why you need them. I do wonder as well. The funny thing is that even if I don't insert those delays, the CBM neatly accepts all the bytes I send. But when displaying the result on screen, it is clear that the received are not used. Receiving a byte means that the CPU has to handle the handshake lines of the IEEE bus. If it doesn't, my PC starts to ring bells in one or another way. As it is accepted, I expect the CBM to USE it as well. And THAT doesn't happen. And I haven't the faintest idea why not. > I think you only mentioned the 8032, so I stand corrected, sorry. No problem. > * OldPet The PET 3032 doesn't set NRFD and NDAC low > * before releasing ATN after a TALK command, > * wait for a NDAC low first! Before sending (the next part of) a directory, I wait for ATN to become (H). In all other circumstances I just gather the data and send it back with my ByteOut command. And this command handles sending the byte using the standard IEEE protocol. Certainly no extra checking of NRFD and/or NDAC after a TALK and/or ATN. Hallo Marko, > Actually, you shouldn't really assume anything else than the > ISO-9660 character set from the underlying operating system > if you intend to make the application portable. The original Commodore name is turned into a 8 char long name by the function Label2Filename in CBM_SW1.PAS. It looks a bit how long Windows names are converted to DOS names using the format 'xxxxxx~1'. And IMHO OS independant. > Now http://www.funet.fi/pub/cbm/crossplatform/transfer/transfer.html > mentions CBM-HD Thank you! -- ___ / __|__ / / |_/ Groetjes, Ruud \ \__|_\ \___| URL: Ruud.C64.org =====DISCLAIMER================================================================= De informatie in dit e-mailbericht is vertrouwelijk en uitsluitend bestemd voor de geadresseerde.
