UPDATE: I hacked the source code for stty
to open /dev/ttyS1 with O_NONBLOCK, which works,
and now see the following after pppd stops:

speed 115200 baud; rows 92; columns 80; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>;
eol2 = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase =
^W;
lnext = ^V; flush = ^O; min = 1; time = 0;

Does this mean anything to anybody?
