FILTRA: A File Transfer Program for the VAX (V00078) (287 words)
As FILTRA includes error checking, the micro computer must have a compatible program such as MODEM which uses the Christenson checksum (XMODEM) protocol.
Compatible programs for micro computers such as the VT180 and the Rainbow-100 are available commercially, and others are in the public domain.
