It varies from one implementation to the next, but generally some or all of the DSP is done in software, all of the line-level protocol (compression, error detection, negotiation, etc) and all of the command-level code are also handled by the host CPU. > If so, then (given the docs on ESS chips used to build that modem) what is > the complexity of writing the missing part?

The DSI softmodem just needed a firmware download, and the support was implemented the wrong way. -- \\ The mind's the standard \\ Mike Smith \\ of the man. \\ msmith@freebsd.org \\ -- Joseph Merrick \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
