- Make sure you have the modem set in error correction mode
(at& on most modems) or no error correction - speed buffer mode
(at& on most modems) depending of your needs. This way, you can
set your terminal to its maximum speed: it will work whatever speed
the calling and receiving modem actually connect.
- Set up your modem to report the error-negociation progress (atw1)
if needed.
- Make sure you have hardware handshake set up both on your modem and
terminal emulator (at& on most modems - mandatory only if you
want error correction)
- Choose the speed yourself - do not let your modem choose the
speed of your connection.
type the command: atn0s37=0
This will choose the maximum speed suitable to your current terminal
settings (14.4kb if your terminal is set to 14.4k or higher).
- if you do not succeed to connect, of if you connect with no error
correction or/and receive lots of stray characters, your line
might be too bad for a 14.4kb connection:
type the command: atn0s37=9
This will force a connection to 9600 baud; even at this lower
speed, you are more likely to get error correction and compression,
or less stray characters, and thus higher effective speed.
- if you still do not succeed to get a good reliable connection,
try atn0s37=6, for 2400 baud..., or
atn0s37=5 for 1200 baud.
You could go even to 300 baud if you are very stubborn, with
atn0s37=1...last chance.
