Using DOS Connect to Back Up Files to a PC
1. Connect the HP 95LX and the PC, using the serial cable from the Connectivity
Pack. If possible, power the HP 95LX with an AC adaptor while using DOS
Connect. The connection with DOS Connect causes a significant power drain
and will erode your battery life.
Make sure that you've set up DOS Connect properly (see pages 94-95).
On the HP 95LX, make sure all System Manager-compatible applications are
closed, highlight the DCS93 EXE program in the Filer and press (NIE).
The HP 95LX will be the server.
On the PC, move to the directory containing the DC935. EXE file and type DC95
to run the program. The PC will be the client. You will see information on the
screen pertaining to the connection. Most important is the mapping of the
drives. Since you'll be working from the client's (PC's) perspective you need to
know how it addresses each HP 95LX drive. Note thatdrive C# onthe HP 95LX
is now called something else (E:, F :, etc.) by the client PC.
. You can now use standard DOS commands to copy the files from HP 95LX
(acting like another PC disk drive) to the PC directory containing the backup
files. The XCOPY command is a good one for selecting all the files in a directory
(e.g. xcopy f :\data\#*.* c:\cpack\hp95bak). Ifyou want to back up
only certain files—not all of them—use the ATTRIB +A command to set the
archive bit for those files you want to backup. Then add the /M switch to the
XCOPY command (xcopy f:\data\*.* c:\cpack\hp93bak /m)*
However, you accomplish the backup, you should consider putting the proce-
dure into a batch file that you can run after DOS Connect is launched.
*The ATTRIB commandisn't available in the ROM version ofMS DOS on the HP 95LX, so you must
either load it into RAM on the 95LX or execute it from the PC during the DOS Connect session
in order to "mark" the files you want to copy.
