Почему может не работать простейший интерфейсный кабель? Спаяно и подсоединено все правильно. Сигнал от передатчика доходит до материнской платы (10 контакт LPT1). Операционная система Win98, адрес LPT1 -378h, IRQ 7. Причем не работают оба драйвера и …32-битный VXD, и …16-битный DLL.
Не работает же и интерфейсный кабель на PIC12C508 на COM порт. Микросхема, правда, с буквой А, т.е. PIC12C508A. Все спаяно и подсоединено без ошибок. Контроллер на выход ничего не выдает.
… во всех схемах коллектор Q2 должен быть подтянут к Vss через резистор, так как указанные выходы PIC открытый коллектор имеют.
IMHO во ВСЕХ приведенных схемах ошибка заложена.
В тех, которые на PIC12C508 - не надо. Там внутренняя подпорка в микроконтроллере.
