some time ago I asked this or that re Mac OSX Serial Port.
Sarah and others sent usefull tips, thank you all. Now I want to tell about what happened:
On my Mac G4 I use the GPort from GriffinTechnologies, which replaces the build in modem. On Griffins website I found a driver for OSX.
Using OSX 10.2.6, Rev 2.1 RC1 (and earlier) I first got drivernames()" -> "gPort,/dev/tty.gPort,/dev/cu.gPort". The third item is the driverName, "/dev/cu.gPort".
Then I wrote a simple teststack with a button "Send" and a field "SendField". Button "Send" owns this script:
----- on mouseup put "/dev/cu.gPort" into DriverName
put "BAUD=9600 PARITY=N DATA=8 STOP=1" into serial set the serialControlString to serial
open driver DriverName for text update
if the result is not empty then
answer the result
end ifwrite fld SendField & linefeed & return to driver drivername
close driver drivername
end mouseup -----
To read the sent serial data I used a Windows Hyperterminal running on a Win-Laptop.
What happened:
I typed "12345" into field SendField, pressed button "Send" and got garbage in the terminal, 1 or two chars, nothing of "12345".
I typed "1234567890" and got two garbage chars I again typed "1234567890" and got two garbage chars I again typed "1234567890" and got about 12 garbage chars.
This cycle was repeatable.
I typed "1234567890123456789012345678901234567890 1234567890" and got:
"12345678901234567890123456789012345678901234567890", followed by NewLine.
After that, I tried again with "12345" and got garbage (see above)
I dont know at this time, if it is a revolution- or a griffin-problem. Next I will bugzilla it.
I hope to get next week a USB2Serial adapter with OSX-drive, so I will try again.
Probably someone of you may test it also?
Thanx.
Richard Hillen.
