Re: QL Graphics

Hi again Per Not 100%, but given that almost zero.zero% of apps bother with HW FLASH, you could get a good indication by checking a few of the bits that hold the FLASH state toggle in MODE 8 versus GREEN in MODE 4. If you find ANY GREEN/FLASH bits set, there's a pretty good chance that the file hold...

Re: QL Graphics

Hi Per Just to add to Tobias' explanation "The original QL mode 8 layout "emulates" 512 pixels horizontal resolution in 256 real ones. ": Even in Mode 8, the OS addresses horizontal pixels as though there were 512 - any accesses to odd-numbered x-axis pixels in Mode 8 are rounded...

Thanks, Martin!

Time to try... I'll report back here at the other end of the weekend.

Re: Nested TRAP #3 I/O calls in SMSQ/E...

Hi Tobias - and thanks very much for that! As for handling ERR.NC from the SER driver Trap - I have designed the 'Message Queue' handling (that will sit alongside the SER driver as a scheduler-loop task to manage asynchronous replies from the uC - maintaining state of each open connection) to captur...

Nested TRAP #3 I/O calls in SMSQ/E...

Hi everyone Further to the on-going development of the QLAN to USB Bridge adapter (for emulators such as QPC), I am in the thick of researching how best to implement the calls to the Serial driver in SMSQ/E from _inside_ the (physical) NET IO driver. (and onwards to the microcontroller's USB/virtual...

Re: Behaviour of SER_BUFF in QPC & SMSQ/E

Hi Tobias, Marcel and other posters :-) In summary, looks like my earlier conclusion that the size of buffer internal to SMSQ was causing the comms problems/fragmented USB packets with the uC were a red-herring after-all. I don't hit the problem these days - I'll try removing the SER_BUFF call altog...

Re: Behaviour of SER_BUFF in QPC & SMSQ/E

Interesting....

Thanks Tobias. I'll look again at why I appeared to see problems communicating with the uC via Serial/USB on QPC2, without extending the buffer size using SER_BUFF.

It was an early-on observation, whilst still debugging the uC code, so maybe a red-herring...

Re: Behaviour of SER_BUFF in QPC & SMSQ/E

Hi John

Thanks for that - that was my assumption as well - namely that any future channels opened to a given port would inherit the latest buffer-size settings - similar to the way BAUD works, for example.

Let's see if anyone else here can confirm or correct this understanding.

Re: QL 34th Anniversary new hardware.

AWESOME Dave!

I'll save my pennies ready for Valentine's Day and divert some funds from the traditional wife's pressy (don't tell her!)

I also wonder what it would take to convince SMSQ/E to talk at 430k...
