I have written a program to communicate with a device through COM port 1.  This device can be controlled using Hyperterminal in windows (using ANSI emulation)
I need to send the up arrow key to the device but I can't seem to get it working properly.  
I have a function Send which works (since it is able to initialise the device) but when it comes to the up arrow part the device refuses to work.  I think its what I'm sending across that's wrong (not very sure what represents up arrow key in ANSI).
Can anyone tell me what I should send across to tell the device I'm sending a up arrow key?
