Yes I just put that in there, for you to feel familiar and comfortable.
It's rather trivial to write/modify the complete pop/smtp in ETHO.
Here's some more code snippets, which I had to look at to add TxAuthenticate:
From the RFC where you have to give: UserID
	Connect(S, host, POP, res);
		IF res = 0 THEN NS.ReadString(S, s);
			IF s[0] = "+" THEN SendCmd(S, "user", user); 
------------> which goes to:
-> SendCmd(S: NS.Connection; cmd, arg: ARRAY OF CHAR);
->  NS.WriteBytes(S, 0, i+2, buf)
WriteBytes (C: Connection; pos, len: LONGINT; VAR buf: NetBase.Data);
->	TYPE
		IPAdr = NetBase.IPAdr;
		Connection = POINTER TO ConnectionDesc;  <-- C: Connection
		ConnectionDesc = RECORD
			res: INTEGER;
		END;
		
	TYPE
		IPAdr = ARRAY 4 OF CHAR;    <-- NetBase.IPAdr;
		Data = ARRAY OF SYSTEM.BYTE;
		Sockaddrin = RECORD
			sinfamily: INTEGER;
			sinport: INTEGER;
->			sinaddr: IPAdr;
			sinzero: ARRAY 8 OF CHAR
		END;
============================
Now lets get back to the real problem:
I'll consider the 'Mailer' because I'm most familiar with it
compared to News & http-fetch.

LNO is running on linux. `pstree` shows that it's a descendant of `bash`

A=>LNO: Mailer < ........<ser-port < modem

B=> Linux < pppd chat script<...<tttyUSB0/1 <wireless-modem

The final target hardware is a netbook, which has NO ser-port,
but I can test on a PC which has USB and ser-port.

I connect to the-net via the linux-chat-script;
and then I tried to 'talk via LNO' by having /dev/tty1 linked to
/dev/ttyUSB0. It fails and LNO hasn't got `ping`to help test.

Firstly I linked BOTH /dev/modem for Linux and
 /dev/tty1 for LNO  /dev/ttyUSBO, but that
 seems strange.
 
 This is really a problem for kernel-programmers?
