Payment method

[RitwickGupta]

Hi,

I am making a program which allows you to open a new screen for payment when my payment option is clicked on tender screen. This interface for payment will be opened by a DLL function which will be called by my ISL code and I was hoping to return back values like Status and Payment_reference_code to ISL function to tell if the payment was a pass of a fail. After that I will close the current Check if the payment was a Pass.

What I want to know is do I need to use TxMsg for my method? I am unclear about when to use TxMsg and How do I send that TxMsg to my third party system.

Also, how do I close a Check on POS through ISL code?

Thanks

So I am using a TCP server program to simulate the PMS. I can send all the data needed using TxMsg command, but I don't know what to send back from the PMS to my ISL code in SIM. My code looks like

var ref             		 : A32 \ 


event inq : 1 //Use Inquiry key #1 to get order info.

//Doing menu stuff here

TxMsg "Pay", @ttldue, @Cknum, menuItemCount, menuItemName[], menuItemCount, menuItemTtl[], menuItemCount, menuItemQty[]

waitforrxmsg "Communicating with Payments..."

LoadKybdMacro key(9, 199)

loadkybdmacro makekeys(total),@key_enter
loadkybdmacro makekeys(ref),@key_enter

endevent


event tmed : 199
window 7, 50, "Payment Info"
display 1,2, "Total: ", total
display 2,2, "Reference Code: ", ref
waitforenter
endevent

event rxmsg : *
rxmsg ref   
endevent

I want to send back a "Yes" or a "No" back to rxmsg. What should be the msg which is being sent back to SIM from the TCP server?
