Thanks to those who've reply. I'm still working on it and will let you
know how it's finally fixed.
I don't how there could be an extension involved because when it works,
it works whether I start with shift-key-down or not, likewise when it
doesn't work. But then, there is a "Serial Tool" extension....
My port has gone from bad to good to bad in the last couple days while
retesting. In general, restarting does not help, but picking up the
computer definitely sometimes allows a short file to be transferred. I'm
still not sure it's hardware, though. Typing as a "dumb terminal" at 50
baud often works, but when I start typing to fast it gets garbled.
Again, when it is "bad", large files (which require periodic handshaking)
or high bit rates are impossible. TechToolPro has a serial port test
which tests "good" when the port seems to be working and "bad" when the
port is not working. (You have to put a modem or home-made loopback plug
on your serial port during the TechTool test).
