There are three basic types of internal modem: 1-Modems that take the full AT command set through a serial chip (or hardware simulacrum thereof). 2-Modems that use the CPU to interpret the AT commands but all codec and compression functions are performed in hardware. 3-Modems that use the CPU to interpret AT commands and some of the codec and compression functions. I believe the original RPI modems were of class 3 above and therefore sucked. Most V.90 Winmodems are actually of class 2 and do not suck as badly as the RPI's. Many internal V.90 modems are class1 and therefore FreeBSD friendly. Most are PnP, though. WARNING: I am not a modem expert. The classes above are strictly my own and made up 3 minutes ago based on my observations of the current consumer modem "scene". YMMV. I do have an external V.90 modem that does not require special software drivers to work. Give it the appropriate AT string and it goes! -- Dave Alderman dave@persprog.com is changing to dave@mmrd.com dwa@atlantic.net -or- dwald@earthlink.net -or- dalderman@compuserve.com -or- dwa@hal.cen.ufl.edu To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
