These modems are based on the Rockwell RC144DPG chipset with no hardware error correction protocols which used so called RPI - Rockwell Protocol Interface to emulate them on the PC's CPU. This bastard comes from Rockwell itself RPI modems and must die.
The Windows 95 TM drivers for the Courier modem have the wrong command
&L2 which causes the modem to respond ERROR during
the initialization process. To avoid this, you must download the fresh
.inf file version from the U.S. Robotics
FTP site or edit the file mdmusrcr.inf at the Inf
subdirectory of your Windows 95 directory, find and remove &L2
command and save this file back. After you do either of above, you need then
to reinstall your modem.
You should note also that old Windows 95 information files doesn't contain any records related to the 31200 and 33600 speeds both for Sportster and Courier modems. To connect properly at them you should also either download the new version of the information file or edit the existent to add the desired speeds manually.
