I tried the external Sportster under 4.8 but after it wouldn't work,
I upgraded to 5.1 to lower the chances of having to go through this
again when I did switch.

I have modem manuals and played with dip switches and lots of AT
commands including "ATE1" ("keyboard commmands"), "ATF0" (I think
that's only for data that the modem sends out the phone line), "ATX4"
("result codes"), re-init commands ATZ, ATZ1-ATZ5, AT&F1, and many
others.  I've been through this several times before (on Linux) and
think I know what I'm doing (except I've never understood the
interactions of "stty" and serial-port-using programs like terminal
emulators.  It's strange that "ATI" gives it's results if I press
keys, but "AT" or "$" don't.

I've found a place to do my FAXing, so the pressure's off on getting
this fixed.

BTW, my other question was about the dmesg files, but I should have
thought of the HISTORY_SIZE thing for at least the console.
(/var/run/dmesg.boot has 943 lines of nothing I care about.)
Someone suggested "kern.consmsgbuf_size=16384".

Thanks.
