Send block / HEX / Dec to serial port

[cchalmers83]

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)

Send any character to 8005U to open it

 

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

 

echo a > com3

Has some info and seems that the above method from dos would work.
