1 /*
2 * One of several FreeCalypso extensions to RVTMUX is TCH bit access
3 * logical channel, and we would like to handle it specially in rvinterf
4 * because it's extremely chatty, sending a frame every 20 ms. If we
5 * were to output every TCH frame in our regular log, that log output
6 * becomes useless as everything else is drowned out. Therefore, we
7 * implement a hiding mode by default: we only count how many TCH packets
8 * were exchanged in between other messages of interest, and report these
9 * counts.
