- Well, they would be, if Sun drivers were available for it.. The only

- There are other manufacturers with parallel port modems such as ZyXEL,

- If you're going to be transferring primarily non-compressible or
- pre-compressed binary data, 38.4k is fine.. You can expect data
- rates of over 3k/sec for 28.8k connections. For text and other highly
- compressible data, it'll still work, but you won't get the maximum
- throughput because of the 38.4k port limitation.
