tiscr - Man Page

take a screen shot of a graphing calculator

tiscr takes a screen shot of a connected TI graphing calculator. Screen shots can be taken at any time when the calculator is turned on and idle (depending on the circumstances, you may not be able to take screen shots while a program is running.)

The output is written in Portable Bitmap format (see pbm(5) if you have the netpbm tools installed.)

Program Options

-o, --output=filename: Write output to filename (PBM format.)
-A, --full: Include the entire screen buffer in the output image (including parts that are not shown on the display.) This only has an effect on the TI-89.

Link Options

-c, --cable=type[:port]: Use the specified link cable (if unspecified, tiscr will search for USB cables connected to the system.) The cable type may be either the full name (GrayLink, BlackLink, Parallel, SilverLink, DirectLink, VTI, TiEmu, UsbKernel) or the 3-letter abbreviation (gry, blk, par, slv, usb, vti, tie, dev). For serial- and parallel-port link cables, a port number must also be specified.
-m, --calc=type: Use the specified calculator model (if unspecified, tiscr will try to determine the calculator model automatically.)
--timeout=n: Wait for up to n milliseconds for the calculator to respond.

Other Options

-v, --verbose: Print out details of link operations.
--help: Print out program version information.
--version: Print out program version information.

Environment Variables
