PosCommands

PosCommands are commands that your interfaces and scripts can send to the POS to affect it. PosCommands can also be invoked when specific products are sold which allows for customised business process. PosCommands themselves are simple directives or instructions to the Pos engine to change or influence sale handling.

A quick example - the PosCommands "sale(new) sale(add,pid,0,10,2.00) sale(pay,cash) saledone?" Will create a new sale, sell item #10 for $2 and pay the sale with cash.
