Chapter 3 SERIAL PORT
The response characters are described below.
Series1 2 Char. This protocol behaves exactly the same as the Series 1
Char except there is a two-character response to the host. The response
characters are described in the following table:
DTR. The printer controls the data flow by sending this hardware signal to
the host. If there is enough room in the printer buffer, the printer will send
a high signal; if the buffer is full, the printer will send a low signal. DTR
tells the host if it is safe to send more data. (If the host sends data during
an unsafe condition, data will be lost.) DTR is not available when RS-422
is selected.
Buffer Size in K
This option configures the amount of memory allocated for the serial port
buffer. The range is 1-16 Kbytes, in 1-Kbyte increments.
NOTE: If you select a baud rate that is 19200 or greater, you may need to
increase the Buffer Size in K parameter from the default to 16 Kbytes
to improve performance.
The factory default is 16.
