Robert - I would be happy without the keyer if I could get reliable keying
using an external key without having to click on the "send" box before and
after each transmission. Could that be provided in the interim? I am
asking because I use MixW via my hardware serial port to key my keyer which
keys the SDR.

In 1.4.1, the new keyer will be disabled. For many of you it is working
perfectly. For those of you with an ACPI 1.0 motherboard, your real time
clock will not support what we needed to get the keyer to work reliably.
With the ACPI 1.0 so called hiperformance frequency is 3.5 Mhz and you
would've though this was adequate. It is not. We have several who are
generating little bursts of white noise and why is clear. We then protect
against that happening and the clock jitter and element spacing goes all
over the map on these ACPI 1.0 mobos. We need a more careful analysis
than we have given this and get reliable tests, etc. We can't allow you to
generate white noise at full power on the air. The old keyer will be back
in charge temporarily.
Frank wrote this keyer to run as a separate process entirely. We were
trying to bend it into a thread rather than a process unadulterated by all
that was going on around it. The primary difficulty was in dealing with
MOX and attempting to handle delays with minimum latency and and insert an
asynchronous thread's ring buffer in place our another threads ring buffer
and it is just all too fragile the way it is written.
Fear not, it will return after a clearer picture emerges.
For those with a compiler, you can enable it but do not expect it to be
reliable as we are in the middle of serious debugging.
