Interface 1 - Noisy Serial Communications
Posted: Thu Apr 19, 2018 7:54 am
Normally the Interface 1 is silent when performing serial port communications.
Today I learnt that you can make a serial port transfer "noisy" by poking the system variable IOBORD (0x5cc6) [border colour during I/O] with a value outside of the usual 0-7 range.
Here's a quiet transfer at 9600 bps followed by a noisy one:

Let's do that again at 19200 bps:
