Solution  1006195.1 :   A wyse55 terminal does not work on E4500 as a ttya console.

Symptoms
A wyse55 terminal serving as a console on an E4500 ttya serial port does not
produce a login or work at OBP (open bootprom), but this same terminal
works fine as a console on a SS5 (SPARCstation 5) ttya serial port and
non console terminal on an E4500 using ttyb.

Resolution
In order for this third party terminal to work as a console on an E4500 using the ttya serial port, the following procedure should be followed paying close attention to the cable configuration.

1.) Configure the Wyse55 terminal for 9600, 8 databits, no parity, 1 stop and
xon/xoff.  Resetting terminal to factory settings should configure the terminal
to these settings.
2.) Attach the serial cable between Wyse55 (AUX) and E4500 ttya.
Important Note: the cable must only include pins 2,3 and 7. The Wyse55 will
not work with a true null modem cable.

3.) Set the E4500 system switch to NORMAL.
4.) Remove the SUN keyboard if one is attached.
5.) Power up the E4500.
Note: EEPROM setting 'auto-boot?=true' for E4500 to boot.
A bootup messages should now start to appear followed by the console login.

Relief/Workaround
Use 'TIP' connection or a laptop running Hyperterm.

Additional Information
If problems persist, attach a SUN keyboard, hold down 'STOP' 'N" keys, power
on E4500, hold down keys long enough until OBP prompt appears.
Make sure not to release the keys too soon.  This procedure will restore the default
eeprom settings. Set eeprom 'diag-switch?=false' to avoid system from running firmware
diagnostics.

For more information on resetting the Wyse55 to factory settings, see:
http://wyse.vecmar.com/faq_wyse55.htm

1.) Power off terminal.
2.) Disconnect any communications and printer cables at rear of the terminal.
3.) Hold down the 'g' key while powering up terminal. Wait until you hear
continous beeps and you see the cursor before releasing the key.
4.) Enter SETUP using  'SHIFT' 'SETUP', 'SHIFT' 'SELECT', 'F3' or 'CONTROL'
'SETUP' keys if in PC-TERM mode for the later.
5.) Press ENTER.
6.) Press the space bar to change the highlighted box to 'YES'.
7.) Press 'F12' to save.
