Modem

This chapter is intended for systems equipped with a modem or
jack.
The built-in modem is able to receive data according to the ITU
standard for V.90 transmissions with up 56 Kbit/s.
Since the power output of modems is restricted due to the regula-
tions of some telecommunication providers, the possible maxi-
mum download speed can be restricted. The actual speed may be
dependent on the online conditions and other factors.
Data sent from the user to the server are transmitted with 31.2
Kbit/s. Prerequisite for this high speed reception is an analogue
telephone line compatible with the V.90 standard and a corre-
sponding compatible Internet provider or company-owned host
computer.
The modem is fitted with an RJ-11 interface, into which a stan-
dard telephone lead can be plugged. If your modem is a combo
card please make sure that it is used only with the appropriate
port.
Warning!
Use only analogue telephone sockets. The modem
cannot withstand the voltage levels of digital telephone
systems such PABX or lines such as ISDN or Broad-
band services.

Serial COM Port

The 9-terminal serial interface (also COM port [COMmunication])
serves to connect serial devices, such as modems, plotters or
similar devices.
The interface is described as a serial interface, because the data is
transferred consecutively (in series).
