This article describes steps to help you troubleshoot problems connecting your Handheld PC (H/PC) to your desktop computer.
The following resources provide information for troubleshooting connectivity problems between your H/PC and your desktop computer using H/PC Explorer:
NOTE: These instructions assume that Windows is installed in the Windows folder on drive C. If you are using a different drive or folder, adjust the following instructions accordingly.
1. You may experience connectivity problems if there is not enough
available program memory. To resolve this issue, follow these steps:
a. Tap the Start button, tap Settings, and then double-tap System.
b. Tap the Memory tab, move the slider to the left to free at least
135K of program memory, and then tap OK.
c. Close all running programs, and then press the Reset button on your
H/PC.
2. On your desktop computer, remove all the communications ports listed
in Device Manager, and then restart your computer. If your computer
does not redetect the communication ports when Windows starts, run
the Add New Hardware wizard to redetect the ports.
3. On your desktop computer, remove H/PC Explorer and Direct Cable
Connection using the Add/Remove Programs tool in Control Panel, remove
all networking components, and then restart your computer. When your
computer restarts, reinstall H/PC Explorer, which will reinstall the
TCP/IP protocol, the Dial-Up adapter, and Direct Cable Connection.
4. Check for multiple copies of the Winsock.dll and Wsock32.dll files on
your desktop computer's hard disk. The Winsock.dll file should be
located in the Windows folder with a size of 42,080 bytes and a date
of 07-11-95. The Wsock32.dll file should be located in the Windows\
System folder with a size of 66,560 bytes and a date of 07-11-95.
Rename any other copies of the files.
5. Lower the baud rate. To do so, follow these steps.
NOTE: These instructions require that your H/PC serial cable is
connected to COM1 on your desktop computer.
a. On your H/PC, tap the Start button, tap Programs, double-tap
Communication, and then double-tap Remote Networking.
b. Double-tap Make New Connection, type a name for the new connection
in the "Type a name for the connection" box, tap Direct Connection,
and then tap Next.
c. In the "Select the device that you want to use" box, tap Serial
Cable On COM1, and then tap Configure.
d. In the Baud Rate box, tap a speed less than 19,200, tap OK, and
then tap Finish.
e. In Control Panel, double-tap Communications, tap the PC Connection
tab, and then tap Change.
f. In the Connect To Desktop Computer Using box, tap the name of the
Remote Networking connection you created in step B, tap OK,
and then tap OK again.
g. On your desktop computer, double-click System in Control Panel, and
then click the Device Manager tab.
h. Double-click the Modems branch to expand it.
i. Double-click Serial Cable On COM1 to open the Serial Cable On COM1
properties, and then click the Modem tab.
j. In the Maximum Speed box, click the same speed (or baud rate) that
you selected in step D, click OK, and then click OK again.
k. Restart your computer.
6. Low battery power may result in connectivity problems. If your H/PC is
equipped with an AC adapter, try to connect your H/PC and desktop
computer while the H/PC is powered by the AC adapter. If your
H/PC is battery-powered only, install new batteries and then
try to connect.
7. If your desktop computer has more than one serial port, connect the
cable to a different 9-pin serial port.
8. Try to connect using a different H/PC serial cable.
9. Disable all lines in the [386Enh] section of the System.ini file that
have either of the following forms:
- device=<filename>.386
- com<number>=irq<number>
To disable a line, place a semicolon (;) at the beginning of the line.
After disabling all such lines, restart the computer. If this resolves
the problem, use the following process to determine which lines cause
the problem:
a. Re-enable one disabled line, and then restart the computer.
b. If you do not experience connectivity problems, leave the line
enabled. If you do experience connectivity problems, disable the
line again.
c. Repeat steps A-B until you have tested each line.
Win.ini file by placing a semicolon at the beginning of each line,
remove any programs from the Startup folder, and then restart the
computer. If this resolves the problem, test each program on the
"load=" and "run=" lines to determine which program causes the
problem.
programs (TSRs) and device drivers causing a problem, restart your
computer. When you see the "Starting Windows 95/98" message, press the
key, choose Step-By-Step Confirmation from the Startup menu, and then
load the following items when you are prompted:
- Dblspace driver (if the hard disk is compressed).
- Do not process the Config.sys file.
- Himem.sys.
- Ifshlp.sys.
- Dblbuff.sys (if you are prompted).
- Do not process the Autoexec.bat file.
- Load the Windows graphical user interface (GUI), choosing to
load all Windows drivers.
If this resolves the problem, isolate the conflict with a TSR or real-
mode device driver using the step-by-step confirmation function.
device drivers, follow these steps:
a. Restart your computer to a command prompt. To do so, restart your
computer, press the F8 key when you see the "Starting Windows 95/98"
message, and then choose Command Prompt Only from the Startup
menu.
b. Type the following lines, pressing ENTER after each line:
cd \windows
ren system.ini system.xxx
copy system.cb system.ini
edit system.ini
c. Add the following lines at the top of the System.ini file:
[boot]
mouse.drv=mouse.drv
drivers=mmsystem.dll
d. Add the following line in the [386Enh] section of the file:
mouse=*vmouse
e. Save the System.ini file and then quit the editor.
f. Type "win" (without quotation marks) to start Windows.
NOTE: If your mouse does not work when Windows starts, it is
likely that it is not supported by the standard Windows mouse
driver. You can install the Windows 3.1 driver included with your
mouse to regain mouse functionality. For information about
installing the driver, consult the documentation included with the
mouse.
