/********************************************************************************
Function:		otcp_strlen

Parameters:		UINT8* str - start address of string buffer
				UINT16 len - buffer length

Return val:		INT16 - (-1) Not a string
						(>=0) Length of string

Date:			12.8.2002

Desc:			Calculates the length of given string

/********************************************************************************
Function:		otcp_bufsearch

Parameters:		UINT8* startadr - start address of given buffer
				UINT16 len - buffer length
				UINT8* str - given searchstring
				UINT8  caps - 0-actual(case sensitive), 1-case insensitive

Return val:		INT16 - (-1) Not found
						(>=0) Start of matched string from startadr

Date:			12.7.2002

Desc:			Seeks given string from given buffer
