Ok, I finaly understand what you say now :-) So, described situation is possible, only when some dialout application previously send chars at different speed and modem remember last speed. So, my comhardclose() fix with comparam(com->it_in) isn't enough, because driver need to send AAAT\r command to modem after it additionly :-( Getty becomes too modem specific after it. It need to send AAAT\r initially too to bring modem to current getty speed first time :-( So, any dialout program which change serial speed becomes getty-killer. We need to document locked devices to getty/gettytab manpage too as mandatory to not allow speed changes. -- Andrey A.
