File Transfer Protocols
When you upload or download files with your modem, the host
computer will ask which file transfer protocol you want to use. Most
communications programs allow you to choose a default protocol.
Your software’s documentation should list the ones it can use (not all
communications programs support all protocols). Zmodem is the
default protocol in
MultiExpress for Windows, and we recommend it for
most transfers. The following is the MEW File Transfer Protocols
screen:

When to Disable Data Compression
The speed advantage hardware compression gives you is entirely
dependent on how much the data being transmitted can be
compressed. If the data is already in compressed form—a .ZIP or a
.SIT file, for example—trying to compress it more will actually slow the
transmission slightly compared to transmitting the same file with
compression disabled. This effect will be most noticeable if your
modem negotiates MNP 5 compression with the other modem. V.42bis
will not try to further compress a compressed file, but MNP 5 will.
The command to disable compression is AT &E14 <CR>. If you use
your modem mostly for downloading long, compressed files from
BBSs, you may want to include the &E14 command in your
initialization string as follows:
AT &F S0=0 X4 &E14 ^M
