Пару дней назад возникла проблема приема входных звоноков - после коннекта у 
клиента не выводится баннер и приглашение к вводу логина. После периода 
таймаута модем отваливается.

Вот что пишется в лог mgetty:

Кстати, вчера при попытке соединения в логе увидел следующую картину -
в течение нескольких секунд mgetty беспрерывно пытался выдать приглашение

Подскажите, в каком направлении двигаться - что-то сам не соображу :-(
