Not every implementation of uucico speaks and understand each
|
|
protocol, so during the initial handshake phase, both processes have to
|
|
agree on a common protocol. The master uucico offers the slave a
|
|
list of supported protocols by sending Pprotlist, from
|
|
which the slave may pick one.
|
|
<P>
|
|
Based on the type of port used (modem, TCP, or direct), uucico will
|
|
compose a default list of protocols. For modem and direct connections, this
|
|
list usually comprises <em>i</em>, <em>a</em>, <em>g</em>, <em>G</em>, and
|
|
<em>j</em>. For TCP connections, the list is <em>t</em>, <em>e</em>, <em>i</em>,
|
|
<em>a</em>, <em>g</em>, <em>G</em>, <em>j</em>, and <em>f</em>. You can override this
|
|
default list with the protocols command, which may be specified
|
|
in a system entry as well as a port entry. For instance, you might edit the
|
|
port file entry for your modem port like this:
|
|
<P>
|
|
<P><P>
|
|
<P>
|
|
This will require any incoming or outgoing connection through this port
|
|
to use <em>i</em>, <em>g</em>, or <em>G</em>. If the remote system does not
|
|
support any of these, the conversation will fail.
