[gnu.bash.bug] flow control

donn@milton.acs.washington.edu (Donn Cave) (12/21/89)

I just put up bash 1.04 on several BSD mini/mainframes here, and it looks
good.  There was one thing I felt I had to do, however - Richard Stallman,
don't read this - I turned flow control back on.

(Specifically, I commented out about 6 lines in readline.c, starting
 with /temp.t_stopc = -1;/.)

It fixed some pretty serious problems with regular terminals, hooked up
on various configurations of RS232 and Ethernet, which basically couldn't
reliably handle the heavy line-editing load on something like autorepeating
\C-p.  It may also have fixed a problem I've had where, somewhere along the
road, things get into a fix where small one-line bursts of output, e.g.
from pwd, wouldn't get to the screen.

Other than the loss of two editing control characters, does anyone see a
down side to this?

I still have a problem that crops up intermittenly on X11 xterm, where small
outputs (e.g., from pwd or jobs) get stuck somewhere before they get
to the screen.

Flow control should be a user setable option (for instance, with a
shell variable "flowcontrol").
