help plz :'( basic noob serial programming question

Hi ppl, I was searching though the forum and can't seems to find an answer, so I decide to post my noob question:

I wrote 2 program, 1 transmit data while the other one receive data. I bought a RS232 adaptor and solder pin 2 and 3 together so that it becomes a loop back cable to the same port (If I transmit from port 1, I should receive from port 1).

However, when I start tranmitting on 1 program, and start the receiver program, vb always ask me to debug the following:

1 If MSComm1.PortOpen = False Then
2 MSComm.PortOpen = True
3 End If

"Error 8005: Port already open (on Line 2)

Its confusing the **** out of me

Thx in advance for the help ^^

I am not a VB Guru, but in order to answer your question quickest, I suggest opening the following.
start/run/cmd.exe, when console appears, type in MODE, a list of all devices will appear, CON, LPT, but most important of available serial ports COM1..., if not, exist the VB IDE, I have seen that if the program being debugged does not close the port, it only closes when VB exits.

Enjoy

Thx heaps !

Problem solved ^^
