SMART ONE V.92 MODEM
32
Using the
ATZ
command overcomes this problem if you have saved all of your setup
parameters in nonvolatile memory. (To save setup parameters in nonvolatile memory in
AT
terminal mode: Type
AT
, followed by the parameter settings you choose, fo llowed
by
&W0
or
&W1
, and press
Enter
. For example, if you type
AT &C1 &D2 &W0
and
press
Enter
, the
&C1
and
&D2
parameter settings are stored in profile 0. Refer to the

Problem:
Your modem disconnects while communicating with a remote system.
Solution:
The remote system has hung up.
The telephone line disrupted your call. If your telephone service includes Call Waiting,
turn it off if possible before making modem calls. You can usually temporarily disable
Call Waiting by including
*70,
(the comma is part of the command) or selecting it as a
prefix with the telephone numbers in the software’s dialing directory.
Problem:
Random errors occur or data is missing
Solution:
Use the MNP or V.42 protocol if the remote modem supports one of these
protocols. See the table on page 32 for more information. Select a lower baud rate in your
communications software and place the call again. If both modems are using the MNP or
V.42 protocol, the only way this can occur is if your modem and communications
software are not using the appropriate flow control. Configure your communications
software for
RTS/CTS
(hardware) flow control. Your computer will now pause for the
transmission to be stored.
Problem:
Data appears garbled on the screen.
Solution:
Your communications software character set-up (start bit, data bits, stop bits,
and parity bit) may 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 normal-
ly use 8 data bits, NO parity, and 1 stop bit (
8, NONE, 1
or
8N1
). The second most
common setting is 7 data bits, EVEN parity, and 1 stop bit (
7, EVEN, 1
or
7E1
).
