This is the driver I used to configure a Boca 33600 ACF Modem onto a Windows 95 and 98 system. After installing the driver, Windows 95 and 98 recognizes the modem as a Internal Fax Data Plug and Play 33600. The driver does work as I used the modem to upload this driver file! Have seen lots of requests for this, so here you go! The chipset on the modem I configured is a Rockwell RC336ACFA.
