- Better to have a modem that does not only MNP 4 and 5 but also V42 and V42bis.
- V42bis can compress more than MNP5. The place you are calling might

- Yes, data compression really works. I have sent files using V42bis
- where the time to send was only half what I would have expected from
- the byte count and the phone line data rate. MNP5 would have been almost
- as good.
