Hi All,
What is the Cocoa-fied way to communicate via a serial port?
Using a kext to support the Prolific PL2303 chip and a shell utility
like cu, it is possible to communicate via many USB-based serial
ports. (For those who need it, the kext is at sourceforge.net/
projects/osx-pl2303.) I am writing a Cocoa app that needs to
communicate interactively with a device using an in-house message
protocol, as opposed to just sending a file across a link. (If it
were the latter case, I would just spawn a process using NSTask and
send the file across.)
I have written such an app under Windows before. In the .NET
framework, there is a class SerialPort that makes it easy. You can
do everything, including set the baud rate, parity, data bits, stop
bits, etc.
I hope there is something similar in Cocoa (but I couldn't find it).
Thanks all,
Soong
ps, Since I mentioned the kext, I'd like to point out that if you
use VMware Fusion, it is my experience that while this kext is
loaded, a virtual machine cannot connect to the serial port. In this
case, I unload the kext using kextunload, and then it works fine.
There was a discussion about this at http://communities.vmware.com/message/1073355
