I don't think you can use it via a DOS command, but you certainly can switch to another screen, umount /cdrom, swap the disk, and mount /cdrom again. Then go back to the DOS screen and tell it you have swapped the disk.

The automatic way which I included in the above scripts doesnt work for me. I posted a question about it to the group too so maybe someone else knows. Also there is no 'on-demand dailing' support in this version of pppd so you can do somthing like telnet machine and have your modem dial it up and establish a connection. A daemon that can do that is dp-2.3 or somthingk like that but I am having a hell of a time trying to port it to the Linux box. Maybe someone with more knowledge of the internals could do that. I will make the above scripts nice and upload them to sunsite some time soon or I can post them here since they are small enought if there is interest. I hope that will help you get started.

It would be really great if these drives could *write* audio format discs too. Then you could record from a sound card and not have to mess about with tape and stuff. Also, it would be really neat for automatically managing a computer based database of all your MDs. Just pop it in and you can get all the track information, edit it, make up your favourite music compilations etc. Anyone know if this is likely?
