* $Log: drv.c,v $
* Revision 1.14 2004/05/28 13:51:42 reinelt
*
* ported driver for Beckmann+Egle Mini-Terminals
* added 'flags' parameter to serial_init()
*
* Revision 1.13 2004/05/26 11:37:36 reinelt
*
* Curses driver ported.
*
* Revision 1.12 2004/05/26 05:03:27 reinelt
*
* MilfordInstruments driver ported
*
* Revision 1.11 2004/05/25 19:54:15 reinelt
*
* 'make distcheck' bugs fixed
* release number changed to 0.10.0-RC1
*
* Revision 1.10 2004/05/25 14:26:29 reinelt
*
* added "Image" driver (was: Raster.c) for PPM and PNG creation
* fixed some glitches in the X11 driver
*
* Revision 1.9 2004/02/24 05:55:04 reinelt
*
* X11 driver ported
*
* Revision 1.8 2004/02/15 21:43:43 reinelt
* T6963 driver nearly finished
* framework for graphic displays done
* i2c_sensors patch from Xavier
* some more old generation files removed
*
* Revision 1.7 2004/02/15 08:22:47 reinelt
* ported USBLCD driver to NextGeneration
* added drv_M50530.c (I forgot yesterday, sorry)
* removed old drivers M50530.c and USBLCD.c
*
* Revision 1.6 2004/02/14 11:56:17 reinelt
* M50530 driver ported
* changed lots of 'char' to 'unsigned char'
*
* Revision 1.5 2004/01/27 06:34:14 reinelt
* Cwlinux driver portet to NextGeneration (compiles, but not tested!)
*
* Revision 1.4 2004/01/21 12:36:19 reinelt
* Crystalfontz NextGeneration driver added
*
* Revision 1.3 2004/01/20 15:32:49 reinelt
* first version of Next Generation HD44780 (untested! but it compiles...)
* some cleanup in the other drivers
*
* Revision 1.2 2004/01/10 10:20:22 reinelt
* new MatrixOrbital changes
*
* Revision 1.1 2004/01/09 17:03:07 reinelt
* initiated transfer to new driver architecture
* new file 'drv.c' will someday replace 'display.c'
* new file 'drv_MatrixOrbital.c' will replace 'MatrixOrbital.c'
* due to this 'soft' transfer lcd4linux should stay usable during the switch
* (at least I hope so)
*
