Machine B (2.1.90).

I did control-C after a minute or so, once I was reasonably sure the data wasn't coming. The file should have been transferred within a few seconds or so.

Therefore you did not do as I suggested.
Nope, the ftp client is running on machine B (2.1.90), which has an EtherNet connection to machine A (2.1.86), which is the local router (via SLIP) to a CISCO terminal server, which is on the departmental LAN. Trust me: I know what keyboard I'm using :-)
