Hi,

You should definitely check out the microsoft documentation of SerialPort Class. They have
different methods listed for sending byte, int, etc

[KelvinLeUT]

you can use as many as you want. You just need to change the port number in the code.

okay, will this not work if I link a serial port on the back of my computer with a usb serial port? I only have one usb serial port converter. Nothing is happening when I press send or have the box checked. The code IS right. I'm guessing it has something to do with the usb serial port being directly connect to an actual serial port. Any help??

[KelvinLeUT]

if your program indicates that the port is successfully opened then
there shouldn't be any problem of sending serial data. If you have just one converter. Just hook up the TX to RX and open up putty to debug. See if you can send serial using putty first. Next, debug with VS as TX and Putty as RX.

When I try to delete some characters in writeTexBox (while using InstantMS) using back space, nothing happens in the readTextBox. (only some strange characters apper in it).

P.S. Thanks for great series on VS C# ! :)

@kle8309 : Sorry for my English! This is just the fun part :-) My realy goal is to build a small app, which can up/download files to/from an old SMT mounter, via serial...
