I changed the dmascc_cfg command-line interface a little bit (due to the
new S5SCC/DMA support and a few additional timings that can be configured).
Unfortunately, in ax25-tools-0.0.8, the man page documents the *old*
interface.
The *new* interface is documented in dmascc/README.dmascc.
Sorry for the confusion.
AFAICR the most important changes are:
"--dma -1" required to disable dma, since "--dma 0" is a valid dma
channel for S5SCC/DMA.
"--txtime" renamed to "--txtimeout" and requires timeout in *milliseconds*
not in seconds.
