If the ZIP drive has its own device driver (with DEVICE=) than whatever is
in floppy.asm has no influence. Or is it really handled via the BIOS as drive A: or drive C:?
When BIOS boots through it, yes. But even if not, its driver probably hooks Int 13h, so fl_diskchange() has to ask it.
In any case a change to init_readdasd in initdisk.c (+ your change in
dsk.c) may be more appropriate than floppy.asm since the changeline status
of a drive won't change after booting -- and I don't think DOS is advanced
enough to handle hotplugging between non-changeline and changeline floppy drives...
:) Of course, but the point is that the device driver hooks Int 13h, so then asking it whether it supports changeline in fl_diskchange() looks reasonable to me.
I fixed the two debug input redirection bugs with the patch below. Now the redirected output contains two consequtive carriage returns though. Maybe there is a way to remove one of them?
Why is echo_char(LF, sft_idx) called in read_line_handle()? Isn't there a danger than it writes the LF to the input file?
