form for to show data captured from serial port

Hi all

i has the code where navision is capturing the data from serial port, using the comm control ocx, but the idea is show in the form permanently.

who is can give an idea and how to reach it.

PD in the old interface made in VB the cicle was permanet and from it write to txt file, and from txt, the data is readed with navision, so i not want to have two applications for that.
