Communication Values - Definitions
Baud Rate
The baud rate is the speed, measured in bits per second, at
which the printer sends or receives data.
Word Length
The word length specifies the number of bits the printer uses to
define a character. The 9406 printer accepts a setting of 7 or 8
bits, but do not use the high-order bit for data.
Stop Bits
A stop bit follows the data and parity bits to signal the end of a
character.
Parity
Parity is a means of checking the validity of data entering the
printer. The last data bit for a character is immediately followed
by a parity bit. The host adjusts the parity bit so the data bits in
the character, combined with the parity bit, form an odd or even
number of bits.
Data Flow Control
Data flow control is the means by which the printer tells the
host whether it is ready to accept data. DTR (Data Terminal
Ready) flow control is most commonly used with an IBM PC
unless the PC has a special Xon-Xoff program.
In DTR mode, the printer activates DTR when it is ready to
accept data from the host and deactivates DTR when its
receive buffer is nearly full.
In Xon-Xoff mode, the printer sends the Xon character when it
is ready to receive data and sends the Xoff character when its
buffer is nearly full. The Xon character is 17. The Xoff
character is 19.
