4. If your legacy software doesn’t have the correct modem
initialization string, you must change it. AT&F^M, which selects the
modem’s factory default settings, works well for most connections.
(^M is the code for the carriage return character that sends the
string to the modem.) If you need extra time to make a connection,
add S7=60 to the string, like this: AT&FS7=60^M. For
CompuServe, the initialization string should be AT&F\N0^M. If you
use CompuServe’s WinCIM software, change the initialization
string to AT&F\N0\Q1^M for compatibility with WinCIM’s software
flow control. Change the error correction string to \N7%C0, and the
data compression string to \N7%C1. If you want the modem to
always answer the phone, add S0=1 to the initialization string.
Note: To change the modem’s default initialization string, type
the new commands in the software’s terminal window, adding the
command
&W to store the new commands in the modem’s
nonvolatile memory; e.g., AT&FS0=1&W. You can then simplify
your initialization string to ATZ^M.
5. If you are using legacy software, select the port the modem is
connected to (normally, COM3).
6. For maximum throughput when using data compression, set the
serial port baud rate, or DTE rate, to 115,200 bps. (In Windows 95,
select Start, Settings, Control Panel, Modems, Properties.)
7. If your legacy software has an autobaud selection, make sure it is
disabled. Autobaud is for much older modems, and can cause
problems if enabled.
8. If the software allows you to edit the no-connect messages ( NO
CARRIER, BUSY, NO ANSWER, NO DIALTONE), make sure there
is no space between
DIAL and TONE in NO DIALTONE.
9. If you must dial
9 to get an outside line, edit the dialing prefix to
include a 9 and a comma, e.g., ATDT9, (the comma inserts a
pause before dialing the next digit). Similarly, to turn off call waiting
for the duration of the call, insert the disabling code used in your
area, e.g., ATDT*70,. If you are using Windows 95-compliant
software, make these changes in the “How I dial from this location”
box of the Dialing Properties sheet.
