Text Mode
Sends a command message from a TE to the network (SMS-
COMMAND). The entering of text is as specified in the send message
command, +CMGS, but the format is fixed to be a sequence of two IRA
character long hexadecimal numbers, which the ME/TA converts into
8-bit octets (refer to +CMGS). Message reference value <mr> is
returned to the TE on successful message delivery. Optionally, when
+CSMS <service> value is 1 and there is network support, <scts> is
returned. Values can be used to identify message upon unsolicited
delivery status report result code. If sending fails in a network or an ME
error, final result code +CMS ERROR: <err> is returned. This
command is abortable.
