I guess you are using the SMC ports for the ttyS* ? > I want to be able to send any char over the serial link, so I've resorted to > using "raw" mode.

In raw mode you're kind of lost - the SMC's don't have any handshake signals. You could switch to use SCC's instead. We have a modified driver that supports full HW handshake on all SCC's (and you can configure the number and size of I/O buffers to optimize for throughput).
