  WHAT IS A MODEM?                       
     Modem is a compound word: MODULE-

 gim.                                     
     The modem converts computer
 data into an analog audio signal (mo-
 dulation), which can be transmitted by
 telephone line and reach another
 dema.  The remote modem transfers the received

  WHAT IS RS-232C OR EIA-232D?        
 This is the recommended standard (i.e.
 in English RS - Recommended Standard)
 EIA (Electrical Industry Association. Ac-
 Electrical Industry Association),
 defining consistent communication-

 There is practically no difference between the options “C” and “D”
 What difference does it make? The RS-232C standard is equivalent to
 ten to the ITU-TSS V.24 and V.28 standard.       
                                          
  WHAT IS A SERIAL PORT?       
     A serial port is a serial
 connector (connector, socket)
 with its inner contour on DTE or DCE,
 having electrical and mechanical ha-

 serving for data transmission. Since
 some signals pass from the DTE port to
 DCE port, and some signals go to the
 opposite direction, same contact

 is determined from the DCE port by the name of the signals on
 contacts (pins) of the connector. There is also
 mechanical difference in the design of the forks and
 sockets (or, as is often said,
 "male" and "female" connectors).         
                                          
  SYNCHRONOUS AND ASYNCHRONOUS COMMUNICATION          
     There are two types of sequential
 data transfer.  One of them is called
 synchronous, the other asynchronous.   B
 synchronous mode, data is transmitted and
 are received bit by bit and synchronized
 are accompanied by an accompanying clock signal. B
 in asynchronous mode, data is sent by sym-
 character by character (or octet by octet), and
 time intervals between sending symbols
 fishing may change. No special
 synchronization signals are not sent -
 are present, synchronization is carried out via transmission
 transmitted data.                       
     Ports COM1 and COM2 in the PC are
 asynchronous serial ports.
