Hi guys. I would like to use the mscomm cotrol to send out through serial port one byte of data. Any ideas on how to do it? And I would alsow like to know, how to rescieve one byte. Any information on how to do this are welcome.
Best regards to you all!

First, set up your port and open it:
mscomm1.settings = "9800,n,8,1" '9800 baud, no parity, 8 data bits, 1 stop bit
mscomm1.commport = 1 'set to use COM1
mscomm1.portopen = true 'open the port
Then, to send a byte, use the output method
mscomm1.output chr$(27) 'sends an ESC char
To receive a byte, you can either use the event handler or just poll the port. For instance, suppose you had a timer set to go off every half second:
if mscomm1.inbuffercount then text1.text = text1.text & mscomm1.input

I understand the input part. But I would like to send out a variable ( dim as byte ) and not an ESC char ( what is that anyway ? ). Plese Help!

Basically, I just sent out byte 27 which to most printers is interpreted as an ESCAPE character.
But you can use whatever you need.... chr$(18) will send out byte 18 for instance.....

If you installed samples with Visual Basic 6 than you have VBTERM project
When you see this example you will know that.
