AMIGA COMPUTER SETUP

Introduction:
Amiga computer systems are based on the Motorola 680x0 series CPU. It
also incorporates multiple proprietary co-processors to reduce load
requirements on the main CPU. The Amiga is inherently a multi-tasking
system, both from a hardware and an operating-system point of view. As
such, it is completely unnecessary to disable multitasking for high-
speed communications. It supports both XON/XOFF(software) and
RTS/CTS(hardware) flow control. Standard init strings, as shown below,
should be used.


Definitions:

Workbench - Amiga computer's Graphical User lnterface (like Windows 
            on IBM platforms).

Preferences - System configuration utility available through
              workbench.

Priority settings - Every task running on the Amiga is assigned a 
                    task-priority number between -127 and +128. 
                    User programs are allowed to run at priorities
                    between -127 and +20, With 0 being the standard 
                    priority.


To configure your Amiga for high-speed communications, find the
appropriate machine type from the list below, and follow the
instructions for that unit. The list below is essentially divided
according to CPU type. Configure your system preference settings in
Workbench accordingly. After that, you can continue to configure your
terminal software.
______________________________________________________________________

68000 CPU (Stock A500, A600. A1000. A2000 computers)
19,200 bps Maximum transfer rate.

Preference Settings:
*  Baudrate: 19,200.
*  Buffer size: At least 16KBytes.
*  CTS/RTS or XON/XOFF <won't allow both to be selected at once>

Terminal Settings:
*  Set software's Priority to at least 10.
*  Set the Terminal's buffer size to the same as the Preference's
   buffer size.
*  Standard hardware flow control or software flow control init
   string:

Hardware flow control string - AT&F&B1&H1&R2

Software flow control string - AT&F&B1&H2&I2

68020/30/40 CPU (Stock A1200. A2500. A3000, A4000, accelerated A500.
                 A1000 or A2000)

38,400 bps Maximum transfer rate.
57,600 bps with high-speed serial port.

Preference Settings:
*  Baud rate: 38,400 <if 38400 is not possible, set the baud rate to
   the maximum allowed>
*  Buffer size: At least l6KBytes.
*  CTS/RTS or XON/XOFF <won't allow both to be selected at once>

Terminal Settings:
*  Set the Terminal's buffer size to the same as the Preference's
   buffer size.
*  Priority is not as important with these units, but if you find
   you are still losing characters, set the priority to a higher 
   value. i.e. 5 or 10.
*  Standard hardware flow control or software flow control init
   string.

Hardware flow control string - AT&F&B1&H1&R2

Software flow control string  - AT&F&B1&H2&I2
