In reply to bert. I was hoping there is some HHGTTG thing behind port #42.

For name lookups you need tnamed (darpa trivial name server), something that predates DNS.

In reply to ozzmosis. msdos is the most excellent msdos player I'm sure it will work with the 'corrected' libc that mit used, although good pont I never tried anything that much more involved. In one of the dumps there is a note about turning on cr/lf

“however it displays TCP/IP information in decimal not in hex”

I think you mean octal rather than decimal? For example 377 octal is 255 decimal.

That’s a decent effort.

What’s the “msdos” command executing in your setup?

In Linux I was able to run your pcc win32 binaries under WINE (from the command prompt – “wine cmd”), and the resulting DOS binary under DOSEMU.

The C runtime might need a few tweaks since printf(“Hello!\n”) from the DOS binary only sends a LF (0x0A) to stdout instead of the CRLF pair that DOS (and DOSEMU) needs to move the cursor to the start of the next line.
