I have an mac ibook with no serial port. I am buying a usb serial port that will plug into the ibook so that I can use the ibook to communicate with my tc racks and configure them from the serial port. My old win laptop is almost dead and I am hoping this will work. Does anyone use an ibook for serial tasks? Is there a recommended program to get to make this work? thanks eric - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.
