ADAM 4500

Подскажите, где ошибка?

Пишу программу для ADAM4500 (на Си), использую заголовочный файл  ADAM4500.h, постоянно выводит ошибку в строках:

void far interrupt com1_intr(void);
void far interrupt com2_intr(void);

Турбо Си

+ Microsoft Visual Studio.net (по умолчанию)

Это из Borland Builder, в остальных, в том числе и в турбо си аналогично
