READY
Field of Application Statement for ordering a ready signal, for example XON, CTS/RTS or
PE, to be transmitted from the printer on the specifi ed communication
channel.
Syntax READY[<nexp>]
<nexp> optionally specifi es a communication channel:
1 = "uart1:"
2 = "uart2:"
3 = "uart3:"
4 = "centronics:"
6 = "usb1:"
Remarks
The selected communication protocol usually contains some “ready” signal,
which tells the host computer that the printer is ready to receive more
data. The READY statement allows you to order a ready signal to be
transmitted on the specifi ed communication channel. If no channel is
specifi ed, the signal will be transmitted on the standard OUT channel
(see SETSTDIO statement).
The READY signal is used to revoke a previously transmitted BUSYsignal.
However, the printer may still be unable to receive more data, for example
because of a full receive buffer.
For the "centronics:" communication channel, BUSY/READY controls
the PE (paper end) signal on pin 12 according to an error-trapping routine
(READY = PE low).
Example You may, for example, want to allow the printer to receive more data on
"uart2:" after the process of printing a label is completed. (Running this
example may require an optional interface board to be fi tted):
10 FONT "Swiss 721 BT"
20 PRTEXT "HELLO!"
30 BUSY2
40 PRINTFEED
50 READY2
