Hi Kapil,
    Your error "Application has written into Low Memory" , occurs in 
case of mismanaged pointers(trying to write more than allocated space 
or unallocated space). 
    One probable reason might be desired number of bytes(resbytes) 
must be less than the current receive queue size(default 512k) when 
you are calling the function
    SerReceiveWait (UInt refNum, ULong resbytes, Long timeout)

    Your code segment is needed to find the actual reason.

Thanks,
   Manikumar K
