.SH DESCRIPTION
|

.PP
|
|
The \fBtelnet_negotiate\fP function is used to request option negotiation. RFC1143 negotiation (Q-method negotiation) is automatically used by libtelnet internally. If the requested option is not already enabled/disabled as desired, negotiation will take place; otherwise, nothing will happen.
|
|
|
|
The parameter \fItelnet\fP is a state tracker instance created by a prior call to \fBtelnet_init\fP.
|
|
|
|
The parameter \fIcmd\fP must be one of:
