This should go onto the Wiki. Here's what Linux' cu does:

[EMAIL PROTECTED]:~$ stty -F /dev/ttyS0 -a
speed 19200 baud; rows 0; columns 0; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>;
eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S;
susp = ^Z; rprnt = ^R; werase = ^W; lnext = ^V; flush = ^O; min = 1;
time = 1;
-parenb -parodd cs8 hupcl -cstopb cread [-clocal] [crtscts]
-ignbrk -brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr [-icrnl]
ixon -ixoff -iuclc -ixany -imaxbel -iutf8
[-opost] -olcuc -ocrnl onlcr -onocr -onlret -ofill -ofdel nl0 cr0 tab0
bs0 vt0 ff0
[-isig] [-icanon] [-iexten] [-echo] [-echoe] [-echok] -echonl -noflsh
-xcase -tostop -echoprt echoctl echoke

The settings between brackets (mine) are the ones affected by cu(1).

It works!

I also found a few possible causes for "worked before" and "sometimes
works", but I think I'll just leave those for what they are. The issue
has been clarified enough as far as I'm concerned.

Thanks,

Bill
