I was wondering if anybody has any help with this.
I hooked up my computer with TTermPro, set it to 9600, 8, N, 1, N, using Null cable.
I hit enter and I get ERR response, which appears to be correct response, since I did not send any code, just CR.
When I type POWR1 and hit ENTER I get ERR again.
I tried other codes as well as tried to fill up empty spaces with underscores.
POWR1____, POWR0___ etc.
Thanks in advance
