Explanation of settings
Here is an explanation of each string setting, as taken from my
modem manual.
AT%G1 enables a higher DTE rate of 230400. This may not work with all
modems, unless they have a 25Hz clock speed, or fast serial
port connection. Refer to your manual if unsure.
&F1 loads a read-only factory configuration (in this case) Hardware
flow control template. (NOTE – Winmodem
users should set this to &F).
&K3 disables MNP5 compression (which often added latency to
connections).
S15=2 disables retrains.
S11=38 set the duration & spacing, in ms, for tone dialling (You can
increase/decrease this value as you wish).
S27=16 disables MNP 2-4 compression.
S0=0 disables Auto-answer.
Users
of Diamond Supra modems might
want to try the following Init string. It works particularly
well with those that have Rockwell chipsets.
AT&F&K3W2
Port settings
After
entering the Init string, select the Advanced
port settings tab.
Slide each of the bars to
the far right, then Click Ok.
Next
click on Change
default preferences.
For
users that have a 28.8/33.6K modem or a Winmodem
(even if 56K/V90, this will minimize disconnections.) select
the Port speed as
57600. For users who have a 56K/V90 modem use 115200.
Select
Standard EC for Data protocol.
Set
Compression to Enabled. Using the Init string from earlier the laggier components
of hardware compression are disabled.
Set
Flow control to Hardware unless you have a winmodem,
in which case you should set it to Xon/Xoff.
Next
click on the Advanced
tab.
Set Data bits to 8, Parity
to None, Stop bits to 1
& Modulation to Standard.
