Configuring the 3Com Impact Digital Modem 11
After the TurboCom software is installed, proceed to the
“Placing and Receiving Calls” section in Chapter 2 of the
3Com Impact ISDN External Digital Modem User Guide.
Configuration Using DOS
To configure the digital modem for an IBM PC or compatible
computer using DOS:
1 Create a directory on the hard drive, insert the 3Com
Impact DOS & Windows Installation Diagnostic Utilities
diskette into the PC’s diskette drive, and copy all the files
from the utility diskette to the hard drive.
Copy the files to a new DOS directory. For example, to create a
directory dddd on your C drive at the C:\> DOS prompt, type:
md c:\dddd
To copy all files from the diskette to a directory \dddd at the
A:\> DOS prompt, type:
copy a:*.* c:\dddd
2 Execute INSTALL from the hard drive.
At the C:\> DOS prompt, type:
INSTALL
The configuration program launches and presents the
Port Settings screen. To move the cursor around the screen,
use the [Up Arrow] and [Down Arrow] keys. To select a
parameter, use the [Space Bar].
3 Use the [Space Bar] to select the digital modem’s
COM port and COM port data rate.
This sets the speed of communication between the
3Com Impact digital modem and the computer during
configuration.
When you select the port, the standard interrupt (IRQ)
associated with that port is automatically chosen. Select the
COM port data rate based on the data rate required by the
destination digital modem and the maximum data rate
supported by your computer’s COM port.
