need input !!!

hi,

I found this code:

Dim iCOM1 As Integer
iCOM1 = FreeFile
Open "COM1" For Output As #iCOM1
Print #iCOM1, "M" & Chr(13)
Close #iCOM1

When I do this command, I'll get a string back.
Can somebody tell me how.

thanks

all you need to do is this:

Code:

---

Open "C:\hello.dat" for Output as #1
Print "Hello World"
Close #1

dear dimava,

Thanks for your input, but ...

I use the COM1 PORT to communicate with a other device.
When I give the "M" & Chr(13) command, then 1 second later
I get a string back. I need to capture this string through COM1.

I've added comments to the code that might help you:

Code:

---

Dim iCOM1 As Integer

'assigns iCOM1 to the next free file number
iCOM1 = FreeFile

'opens the file COM1
Open "COM1" For Output As #iCOM1 

'the character M and carriage return are printed to the file
Print #iCOM1, "M" & Chr(13)

'file is closed
Close #iCOM1

you should use the MSCOMM control to deal with com port stuff.

plus, always use a variable to store the filenumber, never use '#1' or any other explicit number, because in some cases, one application can overwrite data used in another!
