hello,

in drawterm/cpu.c, we have
		if(readstr(fd, buf, sizeof buf) < 0)
			fatal(1, "cannot read OK in p9any: got %d %s", n, buf);
perhaps this is intended to be
		if((n = readstr(fd, buf, sizeof buf)) < 0)
			fatal(1, "cannot read OK in p9any: got %d %s", n, buf);
but the latter is no help. readstr() returns 0 or -1, and if -1 the buf is not terminated by ‘\0’.
therefore these should be simply
		if(readstr(fd, buf, sizeof buf) < 0)
			fatal(1, "cannot read OK in p9any”);

by the way, how can I debug drawterm.
fprint(2,…) is no effect.

commited, thanks.

just print() should do for debugging.
