CONFIGURATION AND SETUP

2.5 TERMINAL COMMUNICATIONS SETUP

The EVB's serial communications port uses the communication parameters listed in Table 2-3.

Of these, only the baud rate can be changed. For instructions on changing it, refer to 2.5.4

Changing the Baud Rate.

Configuring a dumb terminal for use with the EVB consists of setting its parameters as shown in

Table 2-3.

Many terminals are configurable with externally accessible switches, but the

procedure differs between brands and models. Consult the manufacturer's instructions for the

terminal being used.

One advantage of using a host computer as the EVB's terminal is the ability to generate code off-

board, for subsequent loading into the EVB's memory. It is thus desirable for the host to be

capable of running programs such as P&E Microcomputer Systems' IASM12 or Motorola's

MCUasm assembler. For more information, refer to 3.7 Off-Board Code Generation.

To serve as the EVB's terminal, the host computer must have an RS-232C serial port and an

installed communications program capable of operating with the parameters listed in Table 2-3.

Setting up the parameters is normally done within the communications program, after it has been

started on the host. Usually, the setup can be saved in a configuration file so that it does not have

to be repeated. Procedures vary between programs; consult the user's guide for the specific

program.

Appendix B  Communications Program Examples provides examples of using some of the

commonly available communications programs.
