10.7.6 Mode Bits

Mode bits specify details about the capability of a particular terminal and

usually do not affect printer operation. Mode bits are cleared with the xc

symbol and set with the xs symbol. Some printers use all of the mode bits,

so you must either set them or clear them. The mode bits are speciﬁed as

octal numbers in a 16-bit word format. You should clear all bits by

specifying xc#0177777 before you specify the xs symbol.

Refer to the tty

(7) reference page for a detailed description of the status

bits.

The following is an example of mode bits speciﬁcations:

xc#0177777

xs#044000

As shown in the previous example, xc#0177777 clears all bits. The xs

symbol set to 0110 speciﬁes the ECHO and ECHOCTL mode bits.

Table 10–7 lists a description of each mode bit.
