My mouse is acting very strange in QNX RTP,
it jumps around the place with a mind of its own when you
try moving the pointer and decides to click thing whenever
it feels the urge!
Its a PS/2 Trust Ami Mouse Scroll Pro mouse which I have
connected to a serial port using a PS/2 → serial converter.
It works ok with windows.
Its just when you try to move the pointer it suddenly ends up
jumping of somewhere else on the screen and clicks itself
constantly whcih makes it extremely difficult to try manouver
windows on the screen…

anyone know whats going on here?
Serial mice respond to a request from the system to identify themselves.
Once you identify the mouse, you know what kind of protocol it uses.
PS/2 mice do this in a completely different and incompatible way.
I suspect that inputtrap can’t identify your mouse at all and is using the
wrong protocol.
`inputtrap -V query’ should show you what plug and play ID the mouse is
returning. I suspect it’s just garbage since this isn’t really a serial
mouse.
I get the same jumpish behavior but in a different scenario. I boot into QNX
and I can use my PS/2 mouse just fine…then I switch the signal (via a
switchbox) to other computer and then switch back to the one running
QNX…it starts jumpin’ and clikin’ away…looks like the mouse driver does
not take kindly on loss of signal.

There are a lot of different reasons that the protocol stream from the mouse
can get out of sync with what the driver is expecting.
We are concentrating on a solution that will detect when the protocols
are out of sync and automatically resync. This will fix the vast majority
of cases no matter what the cause.
We are also looking at ways to prevent the driver from getting out of sync
in the first place.
