The Chaosnet remote tape protocol allows any number of ASCII characters in the name specifying the drive. However, DUMP is using the GETSYL routine to input a single SIXBIT word. This is then converted to a ASCII drive name.
It's possible to have a remote tape server running on the same host as a PDP-10 emulator. For the purpose of using the drive name to specify a tape image file, it would be good to allow more than six characters, and also lower case letters. It shouldn't be very hard to replace GETSYL with something to input ASCII characters directly.
