Подробное описание

The TEConnect is base class to connect with trade equipment.

Abstract trade equipment connection object. Object have internal text command interpreter that give access to object functions.

Аргументы

cmd	(in) command text. Command format: <function> '(' <parm1> ',' <parm2> ',' ... <parmN> ')'

Возвращает

- command execution result.

Конструктор(ы)
