    Send block / HEX / Dec to serial port

    Hello,

    I am trying to get my system to open a cash drawer connected to serial port (COM3) and the details supplied in the manual is below. Trouble is I dont know the first thing about this and have no idea how it is possible. Any help would be appreciated. The setup is a point of sale system that prints a receipt and then sends a command to open the cash drawer - details below!

    Thanks in advance for any assistance with this:

    7. How to drive the cash drawers:

    Open the COM port with RS232 parameters: 9600, N, 8, 1
    (Baud Rate:9600 , None Parity, 8 Bit data , 1 stop bit)

    Cash drawer 1 (marked CD1):

    (A) Send any character to 8005U to open it (excepting [ESC] code); any characters means ASCII code from code 1 to code 255. Or refer to enclosed command set in the table.

    (B) Send the block to 8005U with [ESC]+ [ASCII codes] to drive it. The [ASCII codes] please refer to enclosed command set.

    a) 8005U USB working:
    When a correct command sends to 8005U USB, it will trigger the cash drawer and the LED will be turned on, then off, after 1 Seconds delay; the LED will be back to blinking for the next trigger.

    Every ON/OFF designs for delay for 1 sec. to wait for next command.

    Command set for 8005U USB ( Send [ESC] + command code)

    Does echo work? I.e. from the command line:

    echo a > com3
