Hello, I am trying to read real-time serial data from a CAN bus interface using 'fscanf'. The parameters of the string are fixed. The problem is that usually, the first line of the string appears to be incomplete/broken or has some fault codes. This affects the allocation of data into rows and columns I've used in my program according to their position in the string. I want to omit the first line of the string during every iteration. The sample data string is attached below with an indication of broken string (first line of text).
'˜D=37:0E2=00:0D9=69;005AB0DC
:0CC=0000:0CD=0000:0CF=0000:0D0=0000:00D=37:0E2=00:0D9=69;005AB140
:0CC=0000:0CD=0000:0CF=0000:0D0=0000:00D=37:0E2=00:0D9=69;005AB1A4
:0CC=0000:0CD=0000:0CF=0000:0D0=0000:00D=37:0E2=00:0D9=69;005AB208
:0CC=0000:0CD=0000:0CF=0000:0D0=0000:00D=37:0E2=00:0D9=69;005AB26C
:0CC=0000:0CD=0000:0CF=0000:0D0=0000:00D=37:0E2=00:0D9=69;005AB2D0
:0CC=0000:0CD=0000:0CF=0000:0D0=0000:00D=37:0E2=00:0D9=69;005AB334
:0CC=0000:0CD=0000:0CF=0000:0D0=0000:00D=37:0E2=00:0D9=69;005AB398
:0CC=0000:0CD=0000:0CF=0000:0D0=0000:00D=37:0E2=00:0D9=69;005AB3FC
Could someone help me out with this?

Is that a cell array of character vectors? Is it a single character vector with embedded carriage return and newline characters?

If you are reading with fscanf() then just do an fgetl() on the interface and discard the result.
