The sequence (backslash) turns off the VT52's hold screen mode. This mode
prevents scrolling of the screen once it is full until the "scroll" key is hit
or the above sequence is received. The sequence [ turns the hold screen
mode on. No doubt EDT sends this before a lot of it's control sequences to
ensure that the mode has not been accidentally set.
I have a working VT52 emulator which I wrote running on a PC so if you have any
other queries I would be happy to try to answer them.
Hope this is of some use to you!
