frogging
[University of Waterloo] v. 1. Partial corruption of a text
file or input stream by some bug or consistent glitch, as opposed
to random events like line noise or media failures. Might occur,
for example, if one bit of each incoming character on a tty were
stuck, so that some characters were correct and others were not.
See
terminak for a historical example. 2. By extension,
accidental display of text in a mode where the output device emits
special symbols or mnemonics rather than conventional ASCII. Often
happens, for example, when using a terminal or comm program on a
device like an IBM PC with a special `high-half' character set and
with the bit-parity assumption wrong. A hacker sufficiently
familiar with ASCII bit patterns might be able to read the display
anyway.
