What about file systems that have multiple metadata streams, like NTFS?
(Multics? I know, not a SIMH machine. But, the argument is to make a
"universal file transfer tool".) One stream for ACLs, for example,
another for Macintosh AFS (gone now), any number of other streams you
can use yourself. I supposed each one could be a ._blah file, assuming
that is a legal file name. If one system uses numbers for metadata
streams and another uses names and yet another uses different numbers or
names, how are you planning to match them up?
Binary files = bad idea
Text files (including ASCII<->EBCDIC<->BCD) = Kermit
Assuming the machinery of SIMH already supports connecting a serial port
to an IP socket, all you may have to write is something to bridge that
socket to Kermit on your client machine, ala a telnet data stream so
Kermit sees it as a telnet server. Some (all) SIMH emulators already
support a telnet session to a serial port. Then your SIMH system reads
and writes to the serial port using its native device support, and
you—human—cut and paste into the Kermit window on your client machine.
You don't have to run a Kermit on the SIMH emulated machine; the SIMH
machinery captures serial data and send/receives it for you.
I agree with Johhny Bilquist on this one: I don't see any advantage in
reinventing what already works.
The icing on the cake is that C-Kermit can actually connect over telnet,
so that side is also already solved. If your simh instance have a serial
port, and it is mapped to a telnet port (something that simh supports),
then run C-Kermit on a Unix box, and telnet into simh, and you have your
kermit connection all set up.
If someone wants to see this in action, install C-Kermit on your
machine, and start it. Then telnet to mim.update.uu.se (in kermit), and
login as GUEST with password GUEST. This is not a simh instance, but no
matter. It is an RSX system, it has Kermit-11 installed, and you are
connected to something that looks like a serial port on that machine.
Start Kermit-11, give the command "SERVER", and then return to C-Kermit
prompt, and try something like DIR.
Works like a charm.
