5.6 Call via RS-232
The terminal can be used as a Hayes compatible data modem by
using the RS-232 interface. If the device attached to the RS-232
interface does not have the possibility to issue dialling commands
the handset keypad may be used for this.
The RS-232 interface of the terminal has automatic baudrate and
framing detection so it is not necessary to configure this in the
terminal before usage. It is important that the wiring between the
RS-232 interface of the terminal and of the attached device (a PC
for example) is correct. The terminal is of type DCE (Data
Communication Equipment) whereas PC’s for example are of
type DTE (Data Terminal Equipment). DCE’s and DTE’s are
connected by a one-to-one cable. It is also important that the type
of data flow control is known and identically configured in both
devices. This cable is supplied as standard device.
The AT-command to establish a call to a modem with phone
number 39661010 situated at Thrane & Thrane in Denmark is as
follows:
ATD004539661010<CR>
Hereafter the modems can exchange data with each other.
The display on the terminal handset will show how the call
proceeds.
