I had a fiddle with this last month and it was a pain in the
arse. Peculiarly, *TYPE devicefs:$.serial1 returned /nothing/ when I sent
data down serial port 1, but returned gibberish (as expected) from the IR
remote via serial2. (The port physically works, in non-RISC OS land.)
This would've been the perfect solution for me, nevermind all this
modem-modem leased-line stuff :) *serialinfo also says it's not trying
any hardware handshaking or anything like that. (though saying and doing
are two diff. things.) Anyone else tried this? PPPconnect seems sort-of
easy to point to the right serial port, but again nothing goes over it.

ps: Lucent modem chip sits on the EASCS chip-select (asserted for
0x08000000 -> 0x08ffffff). It's a 16550-alike, but think it is
plug-and-pray so ... Presumably it could be set up to a varying address
after 0x08000000? Naturally one would like a standard one like 0x080003f8
but.... :) (can I have a flake?)
