basic-128 unused codes

ZXNet echo conference «code.zx»

From Kirill Frolov To All 4 April 2002

Press RESET immediately, All! Found in the Basic-128 ROM unused parts of programs related to rs232 interface. I'm interested - someone patched the original firmware (I took this one from the collection rom's on Philip Kendall's page) or was it not completed to the end from the very beginning?
