Modem Commands
The HopNet is configured and controlled through a series of commands. These
commands are sent to the modem directly when the modem is in Control Mode or
when the modem is in Data Mode if the escape sequence is enabled. The command
syntax is the same for either method, a one- or two-letter command followed by one
or more parameters. The modem will respond with a two-byte message that indicates
the new modem parameter value. The commands are loosely grouped into five
different categories: Serial commands, Network commands, Protocol commands,
Status commands and Memory commands. Each command is described in detail
below. In the descriptions, brackets ([,]) are used to denote a set of optional
arguments. Vertical slashes (|) separate selections. For example, given the string
wn[?|0..3f]
, some legal commands are
wn?
,
wn0
,
wn3
and
wna
. Most commands
which set a parameter also have a
?
option which causes the modem to respond with
the current parameter setting, e.g.,
wn?
Each modem command must be followed by
either a carriage return or a line feed.
Serial Commands
These commands affect the serial interface between the modem and the host. The
default settings are 9600 bps and protocol mode 0.
