Have you tried the Modems section (21) of the LDP's Hardware-HOWTO?
And a word (question?) about 56k connectivity:
��*�You might be unrealistic about how much available bandwidth is on
your
modem line. Lets do the math for a typical 56k modem connection:
1. 56k modems = 56,000 bits per second.
2. You really DON'T have a 56k modem but a 52k modem per US FCC
limitations.
3. You'll almost NEVER get 52k, the best connection I used to get
was
�48k
4. 48,000 bits per second is 4,800 BYTES per second (8 bits to a
byte +
2 bits for the START and STOP RS-232 serial bits)
5. With an MTU of 1500, you will get (3.2) packets in one second.
Since
this will involve fragmentation, you need to round DOWN to (3)
packets per second.
6. Again with MTU of 1500, thats 3.2 x 40 bytes of TCP/IP overhead
(8%)
7. So the BEST throughput you could hope for is 4.68KB/s w/o
compression. Compression, be it v.42bis hardware compression,
MNP5,
or MS/Stac compression can yeild impressive numbers on highly
compressable stuff like TEXT files, but acutally slow things
down
when transfering pre-compressed files like ZIPs, MP3s, etc.
