This program is part of Netpbm.
pbmtogo reads a PBM image as input and produces 2D compressed GraphOn graphics as output.
Be sure to set up your GraphOn with the following modes: 8 bits / no parity; obeys no XON/XOFF; NULs are accepted. These are all on the Comm menu. Also, remember to turn off tty post processing. Note that there is no gotopbm tool.
There are no command line options defined specifically for pbmtogo, but it recognizes the options common to all programs based on libnetpbm (See Common Options.)
