[Coco] NitrOS-9 printing

[Ed Orbea]

I must be forgetting things. I followed Mike Rowen's set of 
instructional videos "Retro Printing For Fun & Profit" to enable 
printing from my the bit-banger port on my CoCo3 via a Raspberry Pi & 
CUPS to a network printer.

After remembering to do the poke for 9600 baud (LOL) I am able to print 
(eg. LLIST) from RS-DOS successfully

Now, I want to print from NitrOS-9. In my boot file, I have the SCF 
manager, scbbp.dr and p_scbbp.dd. If I remember correctly, those 3 
modules are what is needed

I then use xmode to set the baud rate (xmode /p baud =86) which should 
set the '/p' device to 8 bit, 2 stop bit, 9600 baud

When I execute a simple dir command redirected to the '/p' device (i.e. 
dir > /p), I get no error, the coco doesn't freeze up, but nothing is 
received by the Raspberry Pi and thus nothing is sent to CUPS for printing

I assume that because the same thing happens when I forget to do the 
poke in RS-DOS, that there is a baud rate/stop bit/etc problem with my 
xmode command.

Any suggestions?

Thanks
