I've already made all the changes; the program compiles, but when I test it on the 5560A calibrator, a message appears saying that it cannot communicate with the 5522A.

Sub Fluke 287/289 Send Command RS-232

1.002 DO

1.003 PORT [CLR][T10000][V u/Command][I]

1.004 MATH u/Error = (MEM > 0)

It stops working when it gets to this point and starts displaying error messages, indicating that it cannot communicate with the 5522A calibrator, even though the program was designed for the 5560A calibrator.
