MSALT.INI is a Kermit-MS command file to set up most (not all) of the keys on the IBM PC to work with the ALT key as if it were a "meta" key. If one of these keys is typed while ALT is held down, the ASCII value of the key is sent, but the the 8th (parity) bit set to 1, for instance small "a" (ASCII 141 octal) is sent as 341 octal.
