[sp] I have personally found Realterm quite good specifically for for attaching timing info to the prints received. It is available at: http://realterm.sourceforge.net/ For measurement, I send the output directly to a log file - not displayed on the screen. BTW, Teraterm is my choice for regular use. ~sanjeev [snip]...[snip] _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
