Sending content of file over serial connection.

Hi All.

I have a quick question. I have a file that needs to be sent over a serial connection. I am not sure if it is a file or the content of the file that needs to be sent, this would be subject to test. I am sendin from a terminal to a printer and the printer recieves and prints. The file is here called Test1.LBL and it contains this:

! 0 200 200 240 1
LABEL
CONTRAST 0
TONE 0
SPEED 5
PAGE-WIDTH 400
BAR-SENSE
;// PAGE 0000000004000240
BT 5 1 0
B I2OF5 2 1 30 23 115 999900001190507
BT OFF
T90 0 2 136 59 Hello
IL 124 14 280 14 50
LINE 71 90 334 90 1
FORM
PRINT

So I am looking for 2 ways of doing this. 1 to send the file over serial port and 2 to send the content of the file.

I have the serial port open. What comes next

Thanks in advance.

I have a problem here, though, because when I add using System.IO I only have an option called ports. If I write what you suggested, I get an error. I can see that it iss supposed to work, according to MSDN F1 Help, but how do I fix this

Sune

Error 1 'System.IO.File' does not contain a definition for 'ReadAllLines'

If I get the list of available items after File. I get of what is in F1 help. Readalllines is not there, neither readallbytes.

If I mark the error and F1 I get this: Compiler Error CS0117.

Hope you can help.

OK. How about this aproach instead

SerialPort port = new SerialPort("COM2", 9600, Parity.None, 8, StopBits.One);

using (Stream from = System.IO.File.Open("Test1.LBL", FileMode.Open))

using (Stream to = port)

int readCount;

byte[] buffer = new byte[1024];

while ((readCount = from.Read(buffer, 0, buffer.Length)) != 0)

Here I have a problem with the Stream to a port. What do I need to put other then "port"

Hope somebody has the time to help..
