the serial ports on the atom mainboard are still not working, but today I managed to connect the SCD to a different (centos 5) system and made the following findings (via minicom) which may be of interest to you: 1) it is sufficient to just send the uppercase letter F (without cr/lf) 2) this is what the output looks like: R:12,57;- 1,1;20;12,57;13,18;- 2,1; 1,5; R:12,57;- 1,0;20;12,57;13,18;- 2,1; 1,5; R:12,57;- 1,1;20;12,57;13,18;- 2,1; 1,5; R:12,57;- 1,1;20;12,57;13,18;- 2,1; 1,5; R:12,57;- 1,1;20;12,57;13,18;- 2,1; 1,5; R:12,57;- 1,1;20;12,57;13,18;- 2,1; 1,5; R:12,57;- 1,2;20;12,57;13,18;- 2,1; 1,5; please note the blank between the minus sign and the actual value (but I assume you're just using the first value which should never get negative). > The source is > available in the SVN trunk.
