7.2.2 Terminal Requirements
Any suitable VT100 type terminal emulator such as Windows HyperTerminal can be used to
provide basic functionality, but we recommend that Teraterm is used. A copy of this may be
downloaded from:
http://www
.ascom-telecom.co.uk/transmission/support
This will run on MS Windows 9.x and Windows NT.
Follow the on-screen instructions to install it.
When installed use the Ascom HSBBM icon to connect to the modem. This connects via the
serial port with a baud rate of 9600, 8 data bits, parity of none, 1 stop bit and no flow
control.
For other terminal emulators, these values must be programmed using the appropriate set-up
menu.
Choose to connect via the serial port and once the emulator window has opened press
“Ctrl V” to initialise communications. The following menu should appear:
AM64/1024A V3.0

STEP 3
Press CTRL-V to return to the “Screen Menu”. This time you will see that there are more
options. Simply type the letter to the left of the required menu to enter it.
MOVING AROUND AND CHANGING VALUES
To access other screens, you can return to the “Screen Menu” again by typing CTRL-V and
then choosing the required screen by typing its associated letter.
Use TAB to move around the items on a screen and use the SPACE key to change the option
(check/uncheck a check-box, select a radio button, step through values). Where it is necessary
to edit a field such as a password, it is necessary to enter the edit mode by pressing the SPACE
key, press CTRL-C to delete the current value, type the new value and then press RETURN.
If the change to an item needs to be saved then the message “Save Settings Required”
appears in the top right hand corner of the screen. This is equivalent to the PROG lamp on the
modem. To save the settings, move the cursor to the “Programme” box and press the SPACE
key. The message will then disappear and the change will be saved.
Press CTRL-X to log out of the system.
