- Strictly speaking, that's not true. V.42bis acts on data as it arrives;
- the latency associated with waiting for a block to arrive before deciding what
- to send would be unacceptable in many circumstances.
-
- However, V.42bis does monitor its effect on data and, if it finds that it
- is expanding the data for any length of time (LZ always expands data for the
- first few tokens), it will start sending the uncompressed data in stead. The
- damage is done for the data that's been sent, but at least the modem will
- stop.
