Appendix A - Technical Reference; Main At Commands - US Robotics 33600 User Manual

Appendix A – Technical
1. Type the commands entirely in upper case or lower
case but do not type commands using a
combination of the two cases.
2. All commands, with the exception of A/ and +++,
are preceeded by the AT prefix and are executed
after pressing the Enter/ Carriage Return key
(<Enter>).
3. The maximum length of a command is 40
characters. The modem does not count the AT
prefix character, the Enter key or spaces. On the
other hand, it does count punctuation marks such
as dashes and parentheses.
4. Any missing numeric parameter is considered to be
equal to zero, for instance the disconnect
command: ATH <Enter>, is equivalent to ATH0
<Enter>.
