i think mapping in moto code is to get same device numbers for different dlcis.
so if we remove mapping, device numbers _would_ be different and
we should handle this in userspace.

AFAIK, mux driver should know, which type dlci is:
if (iscmdtty[line]) {
TS0710_DEBUGSTR(&d_buf[1], c);
TS0710_DEBUG("CMDTAG");
d_buf[0] = CMDTAG;
} else {
TS0710_DEBUG("DATATAG");
d_buf[0] = DATATAG;
}
maby this can be somehow detectded from bp.

ok

yep. we can just open all channels on initialisation. but see below.

ok. this looks good to prevent bp from panic, but is this correct way?
