Abstract

An information transmission device comprises a communication cannel, a modem and a central processor, frame storage, a monitor, a keyboard connected by a system channel, which are parts of PC. Additionally, a parallel port and an analog-to digital converter, the main output and output for supplying signal “end of transformation” are connected to the parallel port, output of which is connected to “start” input of the analog-to-digital converter and to modem output , which in turn is connected to the communication channel in both directions. Modem output is connected to the analog-to-digital converter, input – to the parallel port which is connected by the system channel to an information carrier, the keyboard, the monitor, the central processor, frame memory and fixed memory, which are PC parts.
