New Line; Receive Buffer; Transmit Buffer - Intermec EasyCoder PM4i User Manual

transmission is held up awaiting an ACK character from the receiving
unit. By default, ENQ/ACK is disabled.
XON/XOFF is a protocol where the communication is controlled by
the control characters XON (ASCII 17 dec.) and XOFF (ASCII 19 dec.)
being transmitted on the same line as the data. XON/XOFF can be
enabled/disabled separately for data received from the host by the printer
(printer sends XON/XOFF) and for data transmitted to the host from
the printer (host sends XON/XOFF).
XOFF is sent from the printer when its receive buffer is fi lled to 75%,
and the transmission from the host is held, waiting for an XON charac-
ter. When enough data have been processed so the receive buffer is fi lled
only to 50%, the printer sends an XON character and the host resumes
transmitting data. The same principles apply to XON/XOFF sent by the
host, even if the percentage fi gure may differ. By default, XON/XOFF is
disabled for data in both directions.

New Line

Selects the character(s) transmitted from the printer to specify the switch-
ing to a new line. There are three options:
