READY
Purpose Statement for ordering a ready signal, for example XON, CTS/RTS or PE,
to be transmitted from the printer on the specified communication channel.
Syntax READY[]
optionally specifies a communication channel:
1 = "uart1:"
2 = "uart2:"
3 = "uart3:"
4 = "centronics:"
6 = "usb1:"
8 = "uart4:"
9 = "uart5:"
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 specified communication channel. If no channel is specified, 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 fitted):
10 FONT "Swiss 721 BT"
20 PRTEXT "HELLO!"
30 BUSY2
40 PRINTFEED
50 READY2
