Hi, in 2015 remote(5) was trimmed down when tip was removed. It looks like documentation for capability "dc" was also removed by accident. cu(1) still supports this (src/usr.bin/cu/cu.c):
381 if (is_direct == -1 && cgetcap(cp, "dc", ':') != NULL) 382 is_direct = 1; Below patch brings back documentation for "dc". ok?
