Hi all,

I need to send a sequence of ASCII codes using serial port depending on the key pressed of a ribon keybord that is like a 5x5 matrix. Let's say pushing a key located at colon 1 row 1 send ascii 01, pushing a key located at colon 3 row 1 send ascii 03 and so on until four keys and then sends the code pushing a key located at colon 1 row 1 send ascii 05 to instruct my YAESU FT-857 to change frequency.

73,

Fernando - PU2PLL - BRAZIL
