Description

This command-line tool demonstrates how to do serial I/O on Mac OS X. Techniques shown are: finding a serial port, opening and configuring the port, sending an "AT" command to a modem attached to the port, reading the "OK" response from the modem (if any), and closing the port.

This sample code has been updated to include a project that produces a universal binary. No code changes were required for it to run correctly on the Developer Transition Systems.
