4.2 Software Configuration for Windows 3.x or DOS
The following information in your communication software needs to be
configured:
♦
COM Port: You must select the COM Port where the IS425A
connects with your PC.
♦
Data Rate: You can select any one of the following data rates:
600bps, 1200bps, 2400bps, 4800bps, 9600bps, 19200bps, 38400bps,
57600bps, 115200bps and 230400bps.
♦
Data Format: The default data format of the IS425A is 8 data bits no
parity bit and 1 stop bit (8N1) format. Besides, 7E1 and 7O1 are also
supported by the IS425A.
♦
Flow Control: The default flow control is the hardware CTS/RTS
flow control. Of course, the software (Xon/Xoff) flow control may be
your choice.
♦
Initial Setting: At the beginning of your communication software
execution, the program will send a series of AT Commands to
initialize your terminal adapter. You may enter the initial setting into
your communication software to customize the initialization. For
example, for Internet access “AT&F1” or “AT&F2” is recommended.
We suggest these as “Modem Init Strings” unless you have User
Profiles of your own (see Section “
9.4 Profile Descriptions of the
IS425A ).
