8-4 Message Strings Date Code 20010518
SEL-2020 Instruction Manual
Table 8.2: Special Message Sequences for Strings (continued)
Character Comments
\Idstr[:h]/ Initiate a phone call using the given dial string. Only applies to modem
ports.
dstr= a dial string of up to 40 characters. Typically consisits of
ATDT and phone number. See Appendix B: Optional
Internal Modem Information or your modem user’s
manual for more information on dial strings.
h= hang up flag. Set to Y to automatically hang up modem at
end of string. Set to N to leave modem connected. You
will need to send a separate message later to disconnect the
modem (i.e., “\MATH”). (If not included, the default is Y.)
\M Modem Escape String. Sends modem escape sequence to force a modem
into command mode. (The modem escape sequence is a 2-second pause,
issuance of the string “+++”, and another 2-second pause.) Only
available on modem ports. Literal characters in a string after this
sequence will be output, even if the carrier detect input is low.
\Rt;saddr[;n]/ Output register contents.
t specifies the data format.
b=binary word (2 bytes).
c=binary byte (1 byte).
h=ASCII-hexadecimal word (4 digits).
g=ASCII-hexadecimal byte (2 digits).
f=float in ASCII.
i=integer in ASCII.
u=unsigned integer in ASCII.
x=binary byte with XON/XOFF encoding.
y=binary word with XON/XOFF encoding
saddr= register address, using any valid register access method.
(See Section 9: Database.)
n= specifies how many registers to read. Data items are delimited
by spaces for all but b and c formats. One (1) is assumed if you
do not specify.
\SP/ Suppress prompt (on Master port). Do not display new prompt after
message contents.
\Td/ Time delay; use this code to place a delay within string output.
d= time in seconds and may be specified as decimal fraction. (This
time delay will be rounded to the nearest 1/32 of a second.)
Time must be in the range of 0.03 - 2047.
