x48 for Zaurus X/Qt and Nokia 770 (v0.4.3) 05/06/2006

This is a Zaurus port of the x48 HP48GX/HP48SX emulator for Unix/Linux + X11.

The HP-48SX/GX is arguably the best RPL calculator ever made.  If you are interested RPN then checkout http://sense.net/zc/free42 and http://sense.net/zc/nonpareil.

This port has only been tested with Cacko (1.21 and 1.23) on my c860 with X/Qt (.8 and 1.9) for X11, more information about Cacko and X/Qt can be found at http://www.zaurususergroup.com.

The x48 has been patched to provide the following features/fixes:

C-Kermit>set line /dev/pts/1 (look at x48 wire: (under LCD) it may be different)
C-Kermit>set speed 9600
C-Kermit>set carrier off
C-Kermit>set parity none
C-Kermit>robust
C-Kermit>server

Transfer files from the HP as normal.
