I have been using serial bridge (1.0.9) under 10.4.11 but when I upgraded to 10.5.8 my AppleScript broke. It has been suggested that the issue was the AppleScript change to 4 byte unicode. Here is a portion of my script

tell application "Serial Bridge"
send to source "test" string "D"
set restOfString to read string from source "test"
log restOfString using type "Sample"
end tell


set AppleScript's text item delimiters to ASCII character 10 <---- I think the problem is here, did Applescript change?
set theList to every text item in restOfString <---- it does not seem to create a list
set AppleScript's text item delimiters to ","
set listLength to count of theList <---- listLength ends up being 1

Does anyone know if this could be the unicode vs traditional ASCII change and if so how do I address it?

I'm not sure. Turn on the logging in Serial Bridge so that it writes to the Event Log every incoming byte. What is shown?

Does it work if you set the delimiter to CR (13) instead of LF (10)?

Here is a sample (same as it has always been)

I tried the 13 character with no change

That is with the logging checkbox enabled in Serial Bridge? That doesn't look like Serial Bridge's normal logging output for incoming data...

I cleared the window and let it do one query and get this;

Closing Connection "test"

Post the rest of your Serial Bridge script. I need more details on what your script is trying to do with the data.

Here is the entire script;

I am pretty sure the issue is the difference between 10.4 and 10.5 as another source pointed out;
You may be running up against the change to 4 byte unicode text in applescript. I dont know how serial bridge handles this, but if it's passing unconverted single byte, traditional ascii up the pipe to you then you may not be able to compare it against strings you create in AppleScript like "ascii character 10" without converting something somewhere.

Basically I query a 1-wire device and get back a block of data that includes the id and temp in C and F plus humidity if it is there. I then parse through the list to assign the proper temp to the proper field. has worked for years as written but broke when I upgraded to 10.5 so now I get no temp readings.

Code: Select all

write log "----------Quick Query Start-----------" as string
remove unit events "quick query THLinc"
--execute script "quick query THLinc" in 1 * minutes
set TempCheckSum to 0

tell application "Serial Bridge"
   send to source "test" string "D"

What is the other source? Is it another forum thread? If so, please link to it so I can see the background information.

I tried the following standalone script which correctly returned a list with 3 items:

Code: Select all

set myFunString to "hello there" & (ASCII character 13) & (ASCII character 10) & "asdf asdf" & (ASCII character 13) & (ASCII character 10) & "qwer qwer"

set AppleScript's text item delimiters to ASCII character 10
set theList to every text item in myFunString

You can try coercing restOfString into Unicode text, but I'm not sure if that is the problem or not:

Code: Select all

tell application "Serial Bridge"
   send to source "test" string "D"
   set restOfString to read string from source "test"
   log restOfString using type "Sample"
   set restOfString to restOfString as Unicode text
end tell
