COMMAND TERMINATOR (CMT): CMT=c [CMT]
Sets the COMMAND (or "INPUT") TERMINATOR to "c" (where c is a single
ASCII character entered as a hexadecimal byte in square brackets, [01]
through [1F]).
END-OF-TRANSMISSION TERMINATOR (EOT): EOT=$ [CMT]
Sets the END-OF-TRANSMISSION (or "OUTPUT") TERMINATOR to "$" (where
$ is a string of up to four ASCII characters, each entered as a hexadecimal
byte in square brackets, [01] through [1F]). In a multinode network, the last
EOT character must be the same as the CMT character.
NOTE: A working EOT cannot include a character of "[00]," except as a default
value for unused characters. If, for example, you specify a two-character EOT
of "[0A][0D]" and then use the front-panel procedure given in Section 3.a to
interrogate for the current EOT characters, you will be told that "Eot1" = [0A];
"Eot2" = [0D]; "Eot3" = [00]; and "Eot4" = [00]. In fact, the instrument will stop
transmitting as soon as it perceives an EOT character of [00]. Thus, if you
were to enter an EOT of "[00][0D] ...," no EOT at all would be transmitted.

TYPE (TYP): TYP=y [CMT] or TYP=y,N [CMT]
The first version of the command sets the Thermocouple Type to "y" (where
"y" = E, J, K, R, S, T, or B) and enables the internal cold-junction reference.
The second version sets the Thermocouple Type to "y" and disables the inter-
nal cold-junction.
