This is what I posted in the dev thread ("you" != Omega.. but everyone)
My latest fixes allow copying from tipi hosted filesystem to DSK1 on the TI floppy controller, by going into TIPICFG, and pressing 'M' for myarc mode... Then without shutting off the TIPI, go into DM2K. At this point TIPI doesn't have any DSKx's... Now you have just "TIPI." and "WDS1." and they are equivalent locations of the tipi hosted filesystem. But now the Level 2 io routines that are supported, are >4x instead of >1x names... So they are distinct from the legacy floppies.
DM2K can copy with WDS1. as the source and legacy DSK1-4. as the destination. As well as the other way... Of course this may have other issues for you if you have a WDS1 already... I don't know... I can't even remember which piece of hardware provided that. It's all just myths and legends to me.
In TI mode, DM2K can copy from TI Floppy controller DSK1-3 disks to DSK4, or tipi mapped DSK1-3 drives (as long as that isn't the same device name as your real drive).
So, in short, if you want to egress files from your TIPI, you need to be in Myarc/WDS1 mode.
For ingress files and generally have a good time, TI mode should work.
TI Mode is the power on state of the TIPI board... To be clear, when I talk about the TIPI... you have a TI, connected to a TIPI, connected to a PI... TIPI isn't the PI when I talk about the hardware... The System of software also gets spoken of as TIPI.. that spans the TI to the PI... So as long as the TIPI board is powered on, it should remember that you are in Myarc mode or TI Mode. That state is not persisted on the PI.
