Configuring a modem in MS-DOS.

Issue:

Configuring a modem in MS-DOS.

Cause:

It may be required for older computers and or programs that the modem be setup through MS-DOS.

Solution:

The below chart lists all the settings that the DB9 Serial port.

By Default your computer would use Baud Rate: 9600, Data Bits: 8, Stop Bits: 1, Parity: None, Flow Control: XON/XOFF.

To set values from a MS-DOS Prompt you can use the Mode Command; we have listed a few examples to give you a general idea how to use this command.

MODE COM1:9600,N,8,1,P - The below command would set Communications port COM1 to 9600 Baud, with no parity, 8 databits, 1 Stop Bit, and with XON/XOFF (These are the default settings). For those who are using Windows 95, Windows 98, Windows ME, Windows NT, Windows 2000, or Windows XP it is recommend not to configure your communication port this way and instead configure it the appropriate way depending upon the operating system.
