The That's why I don't like silently ignoring the problem. Reporting it nastily should have been good for getting drivers fixed. si.c was relying on TS_CONNECTED but TS_CONNECTED isn't set quite right for it. TS_CONNECTED shouldn't be set in ttymodem() unless TS_ISOPEN is set. If you fix this, then change the recent fix to ttyopen() to set TS_CONNECTED if carrier is on as well as if CLOCAL is set. Bruce
