FWIW, I maintain a Windows VM (on a MacOS X host) for the sole purpose of
running PDP11GUI, and I use an USA19H USB serial dongle connected through
to the VM as a serial interface. I don't know if something about this
setup is particularly detrimental to PDP11GUI transfer performance? It
takes me >3hrs to write a 2.5mb pack this way (at 9600 baud), or a little
over 1hr to read one back. Do others see similar throughput with these
tools?
Yes. PDP11GUI is a great tool but it is extremely slow for dumping disks.
It's not your setup. I restored an RL02 pack this way once (at 9600bps)
and it took a very long time (I didn't time it but it was well over 6
hours). Compare this with restoring an RK05 pack on my PDP-8 using
dumprest, which takes just about an hour...
