Modem Issues

How do I get my modem to report the correct speed?

First, you must have the correct driver installed for your modem.  Without it, the correct speed can not be reported in Windows 95, and 98 Dial-Up Networking or Macintosh Open Transport.  The driver correctly interprets the modem result codes to determine the connection speed.

A driver file is an *.inf in Windows and a CCL file for the Mac.

For programs that do not use driver files, you must use one of the following init strings.

According to 3Com/U.S. Robotics, any init string that includes AT&F1 should report the true connect speed.

For most Rockwell-based 28.8 and K56flex units, the command is W2. (For Rockwell-based PCI modems, the command is MR=2.) However, several commands can override W2, including the S95 commands and the &Q commands. If W2 doesn't have the desired effect, you might try adding S95=0 or S95=1 to the init string.

Tip: You may also want to try one of these generic init strings:

AT&F
AT&F1
AT&F&C1&D2
AT&F1&C1&D2

Tip 2: For K56flex modems, try one of these generic init strings:

AT&F+MS=56
AT&F+MS=56S202=32
AT&F1+MS=56
AT&F1+MS=56S202=32
