Perhaps disallow setting it. --- 15 unchanged lines hidden (view full) --- 71 * o Check for TS_CARR_ON being set while everything is closed and not 72 * waiting for carrier. TS_CARR_ON isn't cleared if nothing is open, 73 * so it would live until the next open even if carrier drops. 74 * o Restore TS_WOPEN since it is useful in pstat. It must be cleared 75 * only when _all_ openers leave open(). 76 */ 77 78#include "opt_compat.h" |
