* DESCRIPTION: Mainline code for the device driver
*
*******************************************************************************/
+// ToDo:
+//
+// Done:
+//
+// 1.2.9
+// Four box EX was barfing on >128k kmalloc, made structure smaller by
+// reducing output buffer size
+//
+// 1.2.8
+// Device file system support (MHW)
+//
+// 1.2.7
+// Fixed
+// Reload of ip2 without unloading ip2main hangs system on cat of /proc/modules
+//
+// 1.2.6
+//Fixes DCD problems
+// DCD was not reported when CLOCAL was set on call to TIOCMGET
+//
+//Enhancements:
+// TIOCMGET requests and waits for status return
+// No DSS interrupts enabled except for DCD when needed
+//
+// For internal use only
+//
