trn-and-Buffering?

[Hart Larry]

Hard to think of a complete subjectline, but I am useing trn on shellworld as a 
single user.  At home in linux ssh to shellworld, while in trn my space-bar is 
only active once the next group of articles are displayed in an index.  If I 
hit the space-bar multiple times, it only acts once.  However, elsewhere I am 
useing a 2400 baud modem-and-tteraterm to telnet to shellworld.  In this case 
running trn my space-bar must go in a buffer, as it catches up much 
differently.  Are their some envirenment variables that we need to set on 
shellworld or on my home linux machine so my space-bar will not be limited to 1 
pess?
Looks like the most current version is 4.0.76 test.
Thanks so much in advance
Hart
