Description INSYS Modem 336/56k 4.1 (UL)

4.5.2 Initial operation using HSComm

4.5.2.1 Serial interface

Control/PC and the modem must be modulated via the following joint settings of

the serial interface:

¾ Baud rate (Data transmission speed)

¾ Format (Start bit, data bits, parity, stop bits)

¾ Data flow control (Hardware/software handshake)

PC Settings

Serial interface settings of the PC (Interface menu) – the current settings are dis-

played in the message bar of the main window.

This setting must also be entered at the application (e.g. SPS), which is later con-

nected to the INSYS modem 336/56k 4.1 (UL).

Settings at the INSYS modem 336/56k 4.1 (UL)

Handshake setting at the modem (Configure menu

Modem):

Auto bauding: With the first AT command, the INSYS Modem 336/56k 4.1 (UL) rec-

ognizes the baud rate and the format of the incoming data and configures itself

accordingly. When the modem doesn’t receive AT commands but user data right

away, the last saved settings are kept.

If more data is available than what can be received by the modem, the handshake

will regulate the data flow.
