+.TH serload 1 19.08.2001 Distribution "SIMpad Serial Download"
+.SH NAME
+serload - Downloading a new image to the SIMpad
+
+.SH SYNOPSIS
+.B serload
+.I [IMAGEFILENAME] [ttyS-PORT]
+
+.SH DESCRIPTION
+.B serload 
+downloads a new image to the SIMpad using 
+the serial port. You need to connect the SIMpad 
+to your PC with the delivered serial crossover cable 
+and execute 
+.B serload 
+with the image name as parameter. 
+As an optional parameter, you can provide the serial port 
+for 
+.B serload 
+to use, otherwise, /dev/ttyS0 is assumed as 
+default. 
+.B serload 
+will ask you to reset the SIMpad to 
+download the new image. Depending on the image, it will 
+be burnt into the Flash or directly executed in the 
+RAM without burning.
+.P
+You can update the operating system, 
+the firmware (PBL), and the bootloader with this utility. Updating 
+the bootloader needs two steps: 1st downloading/burning 
+a special bootloader (the so-called alternativ bootloader), 
+2nd downloading/burning the new bootloader.
