to 1 (from memory) and have it spool to the file, so things on the
emulator side work fine - at least in that direction.

Is anything actually hooked up to the reader?? This is both a software
question and hardware. You can transfer files via serial port, using
PIP, XMODEM etc.
At the most basic level, you can transfer a index hex file load and save
it.
You can also use my simulator to transfer files into and out of images,
and then use NST to transfer those images to the real system. This may
be easier than hooking up serial lines etc.
You can "mount" files for input/output over the virtual serial port. This
means you can mount a file then receive from it into CP/M just like you
would have done with an external PC and TTY emulator (but without the
syncronization problems).
Maybe I'm just being dense, but I cannot seem to get this working. I hit
F3 to stop, then F7 whereupon I mount the input file. Then I 'g' back to
CP/M and try:
A>PIP B:TEST.HEX=RDR:
At this point it just hangs and will not respond to Ctrl-C. If I reboot
the emulator I find an empty TEXT.$$$ file on the target disk.
In the debugger, it is simply looping on the UART status register but
apparently never seeing anything.
I'm not using a config file, which I believe makes the default 'file'.
What am I doing wrong?

Generally the only port I trust is console. and I can
easily transfer files
to any system that uses
a serial console because of that.
I'm not quite understanding that statement. How can I use console if I
need to interact with the keyboard and see output? Wouldn't that prevent
interaction with the emulated machine? How would I tell the emulator that
console is the file input? There's just not quite enough in the docs for
me to form a coherent picture of how things fit together. The sample
config files look like they connect the emulator serial ports to real
serial hardware on the PC, but I see no explanation for how files get
assocated with the emulated UART - only that it's the default to have
files connect to N* AUX (and, as mentioned, I'm only guessing that the AUX
port I/O associates with CP/M PUN: and RDR:).
Yes, I'm very confused :-)
