...

Command to set output format as Tdf and T with Modulus-256

checksum:

>form "Tdf =" U3 4.2 tdf " T =" U3 3.2 t CS2 \r \n

Output example:

Tdf = -15.72 'C T = 24.38 'C C9

Tdf = -15.71 'C T = 24.38 'C C8

Tdf = -15.69 'C T = 24.38 'C CF

...

Command to set output format as Tdf and T, with start of text (ASCII

and carriage return at the end:

>form #002 "Tdf =" U3 3.2 tdf " T =" U3 3.2 t #003

Output example (ASCII codes not visible here):

Tdf =-15.14 'C T = 24.40 'CTdf =-15.14 'C T = 24.40 'CTdf

=-15.14 'C T = 24.40 'CTdf =-15.14 'C T = 24.40 'CTdf =-

15.13 'C T = 24.40 'CTdf =-15.13 'C T = 24.40 'C ...
