To me, that causes issues because you're essentially using the PC as a large tape drive, but the real tape drive had REW/FF/PLAY/RECORD as manual buttons. In essence, the computer operator performed a manual DOS function. You can do little more as a PC. The IEC bus offers the ability to implement a complete DOS on the PC, including directory listings and such. > sending the right commands to the RS-232 port of the C2N232).

I'm still fighting a bug in the JiffyDOS implementation during loads, and there's a myriad of DOS commands like U0> and such left to implement, but the former is fixable, and the latter is just code I need to write, no technical challenges. It works very nicely, though a bit slow. As when I started the project, I intend to get the packet structure and such working and robust over serial, and then migrate to a USB-based AVR device and port just the packet system and my file server code to USB. That should remove speed issues. Though, with JiffyDOS turned on now, I get 4000bytes/sec, which is not too shabby. The server is platform independent, and has no GUI. It is controlled completely via the IEC bus command channel. Jim Message was sent through the cbm-hackers mailing list
