Stop Bits
The number of stop bits specifies how many bits will define the
end of a character. There are two options:
• 1 (default)
• 2
Flow Control
RTS/CTS
is a protocol where the communication is controlled
by currents through separate lines in the cable being set either to
high or low. This option is disabled by default.
RTS high indicates that the transmitting unit is able to receive
characters.RTS low indicates that the receive buffer is filled to
75% (see XON/XOFF).
CTS high indicates that the unit transmitting the CTS signal is
ready to receive data. CTS low indicates that the receive buffer is
full (see XON/ XOFF). In some computer programs, for example
MS Windows Terminal, RTS/CTS is designated “Hardware.”
ENQ/ACK
is a protocol where the communication is controlled
by the control characters ENQ (ASCII 05 dec.) and ACK (ASCII
06 dec.) being transmitted on the same line as the data. The
sending unit transmits
ENQ at regular intervals. If the response ACK is not received, the
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 filled to
75%, and the transmission from the host is held, waiting for an
XON character.
