Hope you are all enjoying the festive period - I'm off work for a while and have revisited a couple of earlier topics...
Noisy serial communications and animated load time bar charts
What would happen if the two were combined? Something a bit like this (clip is trimmed for brevity) :

Here's a binary you can play with if you have Spectaculator - redirect IF1 RS-232 input from this file, FORMAT a baud rate and then LOAD *"b"

Re: A variation on a couple of themes
Let's make this a bit more colourful and much NOISIER!

Here's another binary image to play with

Re: A variation on a couple of themes
Found a cool side effect of emulation - you can drive the [virtual] IF1 serial port faster than 19200 baud
The manual describes the system variable BAUD:
The baud rate can be set at ~22435:

And at ~26923:

Tested with Spectaculator and this image
This isn't going to work with real hardware, all that handshaking and buffering etc
The manual describes the system variable BAUD:
Two byte number determining the baud rate calculated as follows:
BAUD=(3500000/(26*baud rate))-2
You can use this to set up non-standard baud rates
The baud rate can be set at ~22435:

Re: A variation on a couple of themes
It seems that the emulated serial port can be set to transmit even faster than ~26923 baud
How about ~33653 and ~48871 baud?

Receiving at these speeds definitely doesn't work though!
Tested with Spectaculator and EightyOne
Here's the Serial Save utility if interested - press keys 1 (~48871) through to 5 (~19230) to transmit at the selected speed

Re: A variation on a couple of themes
I'm so confused.

Re: A variation on a couple of themes
About what? - non standard baud rates, or something more specific?
Re: A variation on a couple of themes
Oh, those are '~' not '-'.
