serial port reading

[grad_student]

While I read from a serial port, i read two lines of strings at the same time even if a carriage return separates the two readings. How can i avoid reading the second line since i want to read each line of string turn by turn.

I would suggest using VISA and then you can set the termination chatacter to be the carriage return. By using the termination character the read will stop after 1 of three things. An error, the number of byted requested was read, or the termination character is recieved.
