That will depend on the hardware that is sending data to the port.

sometimes you can assign the character that will represent the end of a line or in the manual of the hardware it is specified.

If you are using the COMMPort control that ships with Visual Studio 6.0,
you can use something like a timer to check if you have not been receiving input during a lapse of time.

when the OnComm event is raised you can reset the timer to wait 1 second for example. if timer event is raised, it means that you are not receiving Data, so you should process the info you have.

If you need more help, feel free to ask it.

Use this to make you life simpler. This LIbrary is FREE and has built in routines to get data from COM ports etc. You can use this to get data from COM port and then use

String.split to split data

Refer : http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemstringclasssplittopic.asp

to get information about end of line space etc you would probably need their ascii values get that from here\
