Dear shreshtha. I am testing for UART1 and UART2 using echo, cat programs
I wired cross UART1 and UART2 ( RX1 - TX2, RX2- TX1 ). I am excute that blow command line # cat /dev/tts/2 & # echo teststring > /dev/tts/1 --> I see the string of "teststring" on console # cat /dev/tts/1 & # echo teststring2 > /dev/tts/2 Full fuctional test ( cf. terminal program ) is not applied. As soon as posible, I will try to it. Thank you. ----- Original Message ----- From: shreshtha To: 'SangJae H.' ; [email protected] Sent: Wednesday, December 06, 2006 3:55 PM Subject: Is it tested? RE: Anybody using UART1, UART2 ? (solved) Have you done any testing on the UART1 for verifying its full functionality. Testing like loopback programs, or shifting the console to UART1 etc. If u are able to do that please reply, as we are still stuck on using the UART1. Or any other quick testing mechanism like we do for console/UART0 - cat /dev/tts/0 this will print the character back to the console whenever u type a character in the console. regards, Shreshtha Kumar, Inder ------------------------------------------------------------------------------ From: SangJae H.
