Hi, We are in the process of bringing up our new board and we need to be able to test the second serial port i.e. ttyS1. Is there any command that we can use in u-boot to test this? regards Shlomo Kut Software Engineer MKS Instruments Tenta Products Tel: 972-8-9181015 Fax: 972-8-9181020 www.mksinst.com
