- Not always. V.42 introduces a high latency delay for larger blocks of data
- because the modem must receive the whole block before it can start forwarding
- it to the host. So if you have an application which requires low latency, the
- modem<->computer link must be as fast as possible.

- One example is TCP/IP (for interactive use).
