The software is available for download (in source code form) for Unix/Linux platforms from the Eugene Crosser's (the author's) digital camera Web site, www.average.org/digicam. A list of compatible digital cameras can be found there. Software for MS-DOS, Microsoft Windows 95, and Microsoft Windows NT, in executable and source code formats, can be found at Bruce Lightner's PhotoPC Web site, www.lightner.net/lightner/bruce/photopc/.
photopc [-h] [-v[v]] [-q] [-s speed] [-l device] [command [params]] ...Commands are normally entered at an "MS-DOS prompt". Under Windows, camera control commands can be entered using an "MS-DOS Prompt" window (sometimes referred to as a "DOS box" or "console window"), or invoked using a Windows "short-cut" icon (or a PIF).
To get help on using the program:
photopc -hThis will print a brief (somewhat bewildering) summary of the program's options and commands. For a complete description of the program's options and commands see the photopc manual page. This file, "photopc.man", is included with the software source package in Unix `man' format.
photopc -l devicewhere device is the name of the serial port which has the camera attached. Under Windows and/or MS-DOS, the allowable "device" names are "COM1:" and "COM2:". The default serial port is "COM1:".
photopc -s speedwhere speed is the requested baud rate: 9600, 19200, 38400, 57600 or 115200. The default speed is usually the highest. You may find that with older PCs a slower speed is needed for reliable operation.
photopc queryThis will dump the entire state of the camera including information like the number of photos taken, the amount of free memory, the current date/time set in the camera, the camera's model and serial number, the user-specified camera setting, etc.
photopc image num filenamewhere num is the number of the image to be downloaded and filename is the name of the file to recieve the JPEG image. For example "photopc image 4 photo4.jpg" will download the 4th photo into the file "photo4.jpg".
photopc image all directorywhere directory is the name of the directory to receive the JPEG files.
For example, the command "photopc image all .", will downloaded all images from the camera into the current woring directory, into files named "MMDD_CCC.jpg" where "MM" is the month the photo was taken, "DD" is the day of the month the photo was taken, and "CCC" is a sequence number.
The user can control the program's JPEG file naming algorithm using the "-f" option. Two useful options under MS-DOS are:
-f 1 (image file names are MMDD_CCC.jpg (default)) -f 2 (image file names are YYMMDDCC.jpg)where "YY" is a two-digit year, "MM" is a two-digit month, "DD" is a two-digit day of the month (all based on the the time that the photo was taken), and "CC" (or "CCC") is a sequence number. The user actually has complete control over the file naming through the use of "-f" and a format string...the description of which is beyond the scope of this document.
photopc erase numwhere num is the number of the photo to be deleted.
photopc eraseallThis will delete all photos from the camera.
photopc countThis will report the number of photos currently stored in the camera.
For example, to use serial port COM2 at 57600 baud to query the camera, then download all the images in the camera to the directory "/photos" on drive C: (in "YYMMDDCC.jpg" file name format):
photopc -l com2: query -f 2 image all c:/photos -s 57600A command such as this can be invoked as part of a Windows 95 "short-cut" icon, allowing quick, automatic downloading of a camera with a single mouse double-click.
If you interrupt communication with your camera by aborting the program (e.g., by enter ^C), you may have to turn the camera off and back on in order to restore proper communication.
photopc -z ...Under the MS-DOS operating system, the time zone is set using the "TZ" environment variable. The TZ environment variable can be set with the following MS-DOS command:
set TZ=zzz[+/-]d[d][lll]where "zzz" is a required three-character string with the name of the current time zone, "[+/-]d[d]" is a required field with an optionally signed number of one or two digits specifying the local time zone's difference from GMT in hours, and "lll"is an optional three-character field with the name of the local time zone during daylight savings time. This command should be placed in your AUTOEXEC.BAT file. For example, the following command sets the time zone to Pacific Time:
Under MS-DOS, if the TZ environment variable is not set the program will not apply a time zone correction, giving the same program behavior as with the "-z" command line switch. Under MS-DOS, if the TZ variable is set, but does not satisfy the above described syntax, the time zone correction is undefined (i.e., probably wrong).
Under Windows, unless the "-z" command line switch is set, the program always will apply a time zone correction, as defined by the time zone setting in the Windows operating system. However, if the TZ variable is set (using to the above described syntax), then it overrides the Windows time zone setting, and the program will apply a time zone correction as defined by the TZ variable. Beware that if the TZ variable is set under Windows, but does not satisfy the above described syntax, the time zone correction is undefined (i.e., probbly wrong).
