Setup & SetUp Command 5-8
delay is added to the typical command delays listed in the Software
Considerations section of Chapter 3. Each unit of delay specified by bits 0
and 1 is equal to the amount of time required to transmit one character with
the baud rate specified in byte 2. For example, one unit of delay at 300 baud
is 33.3 mS; for 38.4 kilobaud the delay is 0.26 mS. The number of delay units
is selectable from 0 to 6 as shown in Table 5.3.
In some systems, such as IBM BASIC, a carriage return (CR) is always
followed by a linefeed (LF). The D1000 modules will respond immediately
after a command terminated by a CR and will ignore the linefeed. To avoid
a communications collision between the linefeed and the module response,
the module should be setup to delay by 2 units.
