[En-Nut-Discussion] Problem with VT52 (dev/term.c)

[José Vallet]

We have been using it without problems either.

Here goes a piece of code that does something similar. We use the 
defines provided in term.h to avoid little errors as the one Michael 
noticed.

-------------------------
//Place the cursor in the HOME position
fprintf(lcd_uart, ESC_CLRHOME);
//Print the info in certain fixed position usint VT52 controls
fprintf(lcd_uart, "Vo=%i" ESC_POS 
"%c%cIo=%i\n",stack_volt,32+0,32+8,current);
fprintf(lcd_uart, "Air=%i\n",air_flow);
fprintf(lcd_uart, "To=%i" ESC_POS "%c%cT1=%i",stack_temp,32+3,32+8,temp_d);
---------------------------

Regards
José
