SETTING UP PC COM PORT WITH LA75 SERIAL PRINTER

For Windows applications
------------------------

Printer default settings are different than the PC default communications port 
settings; in order for the two to communicate they need to be the same.

To change the com settings with Windows, get to the Windows main dialog box,

- double click on the Control Panel icon (the Control Panel dialog box appears)

- double click on the Ports icon (the Ports dialog box appears)

- click on settings

- then move the cursor arrow to each parameter box and change the parameters to 
the following:
	- baud: 4800
	- Data bits: 8
	- Data parity: None
	- Stop bits: 1
	- Flow control: Xon/Xoff

After all these changes, then click on the "OK" box; now the previous Ports 
dialog box appers, click on "OK" again, and now the Control Panel dialog box 
appears, click on the word "Settings" and click on exit and you are back to the 
Main dialog box,


For the installation, use the installation instructions.

After the installation, it's important that the printer model appear in the 
installed printer list, and is shown on COM1 and active; it also needs to show 
in the default box (do this by clicking on the LA75 within the installed printer 
listing)

Also, the printer needs to be put in DEC mode via the front panel setting of the 
printer.


For DOS applications
--------------------
For DOS applications, the com port needs to be reset to the settings of the 
printer; as our printers run in serial mode and use Xon/Xoff, the PC must be set 
up as follows:
insert "xon/xoff" in the autoexec.bat file using the edlin command 

type edlin autoexec.bat
at *, type l
type a new line number with an i (like 10i)
type xon/xoff and carriage return,
do a control C
type ex
 
reboot
now use the decmode command to set up com line in PC, type in the following at 
the DOS prompt > decmode COM1:4800,n,8,1,p,b
		 

And to direct the print function, which normally is LPT1 to the COM1 port, type 
the following at the prompt> decmode LPT1:=COM1:

******************************************************************************
The PC default settings for COM1 are 7 databits, and even parity; these are 
different than the printer.
