BASCOM-AVR : Any limit to length in Crc16uni function? : NEWTOPIC

I'm using Crccalc = Crc16uni(buffer1(4) , 1024 , 0 , &H1021 , 0 , 0) to calculate Xmodem-1K CRC, doesn't get the correct CRC, if I use the same code for lengh=128 all is OK. Any idea what is wrong? I used Hpmbcalc to calculate the CRC (it's shows the correct one - the same as Xmodem-1K transmition capture) with the same parameters as the Crc16uni(buffer1(4) , 1024 , 0 , &H1021 , 0 , 0) call.
