Section 4 Serial Controller
4.8
Items shown in capital letters, such as ENTER or OUTPUT must be
used exactly as stated but may be entered in upper or lower case.
Items in lower case, such as addr or count represent parameters
which must be substituted with an appropriate value.
Blank spaces in commands are generally ignored. Thus, LOCAL
LOCK OUT is the same as LOCALLOCKOUT. Spaces are not ignored in
four places: the data part of an OUTPUT command, within quoted strings
in a SEND command, after an apostrophe (') in a terminator specification
(term), and after the semi-colon following the ID command.
The number sign or hash character (#) and the semi-colon (;) must
be present exactly as shown. A comma (,) represents an address
separator. The oblique or slash character (/) or period (.) may be used in
its place as the address separator.
Optional semicolons ([;]) may be used, if desired, for consistency
with other IOtech products.
Items enclosed in the square brackets ([item]) are optional.
Multiple items enclosed in square brackets separated by vertical lines
([item1|item2|item]) are optional, any one or none may be chosen.
No more than one item may be selected.
Ellipses(,,,) within square brackets mean that the items in the
brackets may be repeated as many times as desired. For example
[
,addr ,,,] means that any number of address separator-address
combinations may be used, up to a maximum of fifteen.
Items enclosed in braces or curly brackets ({}) are required.
{ item1|item2} means that exactly one of the enclosed items is
required.
Combinations of brackets are possible. For example,
{ term[term][EOI]|EOI} allows the choice of term, term EOI,
term term, term term EOI, or just EOI, but does not allow the choice
of "nothing."
