The terminal emulation was inherited from the original PropIO project and I
think it got it's terminal emulation module from Vince Briel's PockeTerm.
I have always meant to enhance it, but have never gotten around to it. A
subset of the VT-100 CSI codes is implemented and has always worked well
for me (WordStar, etc.). There are limitations in the display module on
the Propeller that prevent many of the SGR codes from being implemented.
For example, the display driver can only set colors one line at a time,
not in individual character cells. I am aware of alternative Propeller
display drivers that will resolve this, but, have not had time to play with
them.
The screen blanking was added at the request of a few builders. Yes, it is
hard coded. I don't have any simple way of persisting configuration
information on the Propeller, so everything is hard coded I suppose I
could persist configuration information on the host computer and send it to
the Propeller at startup. Again, a matter of time. Screen blanking could
easily be enabled or disabled at build time, so I am open to other folks
thoughts about whether it is desirable or not. Happy to go with the
consensus on that.
The PPP firmware could certainly use some work if anyone is interested in
taking it on... :-)
Thanks,
Wayne
Post by Bob DevriesI guess that means that the PPP is not completely ANSI compatible?
Are there any plans to add CSI and SGR ANSI codes?
I guess the screen blanking is hard-coded also? :(
The above is one of my pet hates... IMHO, in this day and age, with LED
screens, screen blanking is not only un-necessary but quite useless.

Post by Max ScaneHi Bob,
Changing the screen colors can only be done by changing the Propeller
firmware code. With that said, it would be a pretty easy change -- just
a couple constants as I recall.
Thanks,

Thanks, Max.
I found that I'd mis-interpreted the JP1 jumper; it needs to be on

PS: is there a way to change the screen colours?
Post by Max ScaneHi Bob,
Have you checked your PPP card? There is a specific version of
firmware

Also check the PPI power jumpers as I think the PPP is powered

Post by Max ScaneHi all,
I am in the process of adding a ParPortProp to my Zeta SBC.
I'm fairly sure that I have it all connected correctly,
but...
Post by Max ScanePost by Max ScaneThe Zeta is still "talking" to its serial port.
The ROMWBW signon comes on slowly (IMHO).
After a while it says Parportprop not responding.
Does anyone have any clues where I should start looking? Do I
have a
