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
.
