erc-send-command

erc-send-command is an alias for `erc-server-send' in `erc.el'.

(erc-send-command STRING &optional FORCEP TARGET)

This function is obsolete since ERC 5.1;
use `erc-server-send' instead.

Send STRING to the current server.
If FORCEP is non-nil, no flood protection is done - the string is
sent directly. This might cause the messages to arrive in a wrong
order.

If TARGET is specified, look up encoding information for that
channel in `erc-encoding-coding-alist' or
`erc-server-coding-system'.

See `erc-server-flood-margin' for an explanation of the flood
protection algorithm.
