I solved the problem and it was a minor change I made to my code that
caused it.
I was doing some testing with reading the port and how to determine the
end and then forgot I changed it. This is based on Sarah's readPort and
I originally used until recEOL but changed it to EOF (end of file) to
test &
my change caused the problems.
read from driver thePort until recEOL
--read from driver thePort until EOF

Something really strange is happening.
The driver I was writing to mentioned below is the internal modem
on a Mac G4 AGP.
You use the AT commands to control the modem.
I used to be able to enter AT&V and then it would put the
configuration into a field.
The configuration consists of a number of lines of text but not
extremely large.
Now when I enter the AT&V command it puts about nine lines of text
into the field
and then Rev crashes. If I use this program on another machine I
have and enter
the AT&V command it puts the configuration into the field like the
first Mac used
to do. But when I copy the text in the field it was put in Rev
crashes.
This looks to me like some memory/buffer management problems with
Rev to me
but I really don't know what it is. Why did the first Mac used to
list the configuration
without any problem and now only list part of it then crashes Rev?
I have not made
any changes to my knowledge that would cause this. And why can't
the other Mac
copy a small amount of text after writing the AT&V command to the
driver?

When I open a driver port I am able to write to the driver and
close the port without any problems.
I can open the driver port and write to the driver 9 times writing
one line at a time no problems.
After I write the 10th line to the driver Rev crashes.
If I close the port after writing line 9 to the driver I can write
to the driver 9 more times.
The line can have a few chars or a large line of text and the
crash still comes after writing to the
driver 9 times.
How can I clear any buffer or whatever is doing the counting
without closing the port and the
needing to reopen the port to keep writing lines to the driver?
