34 Quick Start and Reference Guide
(you need a Pentium® 133 or faster, or
equivalent).
Problem: Data appears garbled on the screen.
Solution: Your communications software character set-
up (start bit, data bits, stop bits, and parity bit)
does not match that of the remote system.
Check your settings against those used by the
remote system and make sure they match. Pay
particular attention to the parity setting, as
this is the most common difference among
systems. You should normally use 8 data bits,
NO parity, and 1 stop bit (8, NONE, 1 or 8N1).
Another common setting is 7 data bits, EVEN
parity, and 1 stop bit (7, EVEN, 1 or 7E1).
Problem: Your modem doesn’t seem to be compress-
ing the data.
Solution: The compression features are on by default,
but check the following:
Your software needs to use a streaming proto-
col, such as Ymodem-G or Zmodem. Xmodem
and Ymodem are not adequate for compres-
sion.
Your software must be set up to use hardware
flow control (RTS/CTS ON).
Be aware that many files downloaded from on-
line services have already been compressed. In
general, your modem will not be able to further
compress such files.
