I sometimes see that the CPU usage of DCA is running particularly high, even reaching 100%. Why does this happen?

Due to the architecture of the product, the COM port is polled by DCA (it takes complete control of the CPU in that time slice, but then yields immediately). This happens continuously, creating the illusion of 100% CPU usage. Applications should not be affected by this, although it can create a slower speed response in CAD graphics packages or other graphics programs such as screen savers.

2)

Will DynaComm Asynchronous work under Windows 95 or Windows NT?

DynaComm Asynchronous is a 16-bit product that was designed for 16-bit operating systems such as Windows for WorkGroups and Windows 3.x. Older versions of DynaComm were written before operating systems like these were even thought of! Therefore, we would strongly recommend that anyone using a 32-bit operating system should upgrade to one of our 32-bit products. However, DynaComm does appear to function satisfactorily under some versions of 32-bit Windows.

3)

How do I make a trace with DynaComm Asynchronous?

First, you must make sure that you have a connection established. Go into the Transfers menu and choose "Receive Text File". Create an appropriate name (with a dcm extension) and check the "Save Controls" checkbox. All of the commands from this point on are now recorded into the file you specified. When you have completed the trace, you can go to the Transfers menu again and pick "Stop".

4)

Can I choose a different font from the one I use in my Terminal Window for printing documents?

Go into the File Menu and choose the Printer Setup Option. There is a section in here, which corresponds to the Printer Font. If you do not alter this, then DynaComm uses your Terminal font as default.

5)

How do I map a key in DynaComm?

Launch the keyboard mapper onto your screen (you can do this by clicking on the fifth button of your level one toolbar or by executing the script KEYMAP.DCT). Left click on the key that you wish to map and then choose the appropriate state for that key (e.g. Normal, Shift etc.). Choose the function that you wish to associate with that key (e.g. menu command, string Esc). Now the key is mapped.

See the FAQ forDynaComm Asynchronous Keyboard Mapping for more information.

6)

Can I load my custom keyboard into the Terminal Session via Script?

Within the script, type in the following line:

Perform "keymap*mapkeys"("c:\path\mapfile.dkm")

where “c:\path\mapfile.dkm” is the drive, path, and file name of the custom keyboard file.

7)

How can I change the colors on my screen?

You can get to the color mapper in a number of ways. You can reach this by running the script COLOR.DCT, or by looking at the recently run scripts - Colors is the first one within this list. You can also reach the color mapper from the toolbar at the bottom of the screen.

8)

What are the extensions for the different files that DynaComm uses?

Here is a list of the files:

• Dialing Directories - *.DCD
• Script Files - *.DCP
• Compiled Script Files - *.DCT
• Settings Files - *.DCS
• Memos - *.DCM

9)

When I try to select a font from under the Settings : Terminal Preferences, I only have a Courier New available, even though I know that I have more fonts loaded under Windows. Why does this happen?

You may have selected the "Show only True Type Fonts" checkbox under the Fonts section of the Control Panel (under View : Options). DynaComm can only used fixed width fonts (this is a general limitation in terminal emulations), and Courier New is the font shipped with Windows that is both True Type and Fixed Width. Selecting the True Types only will prevent DynaComm from selecting its own installed bitmapped fixed-width fonts.

10)

My modem is not listed in the modem list within DynaComm. Does this mean that I cannot make a modem connection?

You can select the Generic Hayes Compatible (Advanced) option. If the modem is not Hayes compatible, then the modem initialization strings will have to be customized from the Modem : Settings dialog box, according to the modems specifications.

11)

How do I associate a different keyboard mapping file (*.KBM) to each of my settings files when they are loaded?

Perform the following steps:

Step 1: Create a settings file that is configured to access your host and save it. (Example: HOST1.DCS)

Step 2: Map the keyboard for your first settings file, and save it under a new name. (Example: NEWKBD1.KBM).

Step 3: Create a script that loads the settings file and applies the corresponding keymap. An example of the script would be:

load "HOST1.DCS"

perform "Keymap*MapKeys"("c:\Dynacomm\NEWKBD1.KBM")

Save the script with DCP as the extension, such as HOST1.DCP. Compile the script and it will create a binary file with the same filename except the extension will be DCT.

With Windows 98 SE, I receive an error message when I try to connect via Winsock. Why does this happen?

This is a result of Microsoft's incorporation of Internet Explorer into the operating system. Internet Explorer version 5.0 and above have been designed to work with a newer version of Winsock than DynaComm Asynchronous was designed to work with. Because Windows 98 SE has IE 5 integrated into the OS it is not recommended that this be removed (and is difficult to do so regardless). As DynaComm Asynchronous is considered to be a mature product, there are no plans at this time to do any more revisions to the code. The best solution to this problem is for the user to consider upgrading to DynaComm Connectivity Series as this is a true 32-bit application that accommodates the current versions of Winsock.

When installing DynaComm Asynchronous on a PC running McAfee Anti-Virus software, I get a message telling me that the DynaComm.ex_ has a virus but no virus name is given.

This McAfee VirusScan message appears when a time out occurs during a file scan. If DynaComm Async is installed from a CD, the scan performs quickly and no error occurs. If DynaComm Async is installed from a floppy, the scan times out and displays the erroneous virus detection message. McAfee is developing a fix for this in the next release of VirusScan.

To work around this problem, do the following:

1. Shut down the AVSync Manager service.
2. Open the registry and add the following registry key:
   
   HKEY\LocalMachine\Software\Network Associates\TVD\Shared Components\
   On Access Scanner\McShield\Configuration\DontReportTimeouts=1
   
   Note: This entry is a DWord key.
3. Restart the AVSync Manager service.
