: Is `automatic' (well, semi-manual) speed selection an option for you?

If I lock dte at 19,200 to 57,600 then low baud users get a lot of 
garbage.  This is an IBM Easy Options modem, and seem to be not quite 
standard.  I finally solved the problem by setting it up to cycle from 
9600 to 57,600 although I wish it'd do it with a newline instead of a 
break :/  Not to be rude, but a lot of the bbs'ers in this area are 
either not real bright, or fairly lazy.  (to give you an example all my 
login screen says is

Type CBM at login
login:

and some of them STILL mess it up (trying to enter their names, or "new" 
instead...)) so I have to make this all as simple as possible.  In the 
next version of the software, I think i'll write my own getty that scans 
for the connect message and adjusts speed to match...

Thanks for your reply :)
