Shell user input length limitation

There is a simple shell (does not matter sh, bash or KornShell (ksh)) script:

#!/bin/ksh

read userInput

I have two Solaris 9/10 servers. On one of the server I can type long string while read is running. But on another server I can't type string with length more than 257 symbols.

What kind of limitation is this?

This is probably the terminal input queue size limitation, MAX_INPUT constant is the maximum size of that queue.

Can't exactly remember but kernels can be customized (settings) to handle new values for such constant. Refer to your system kernel config documentation.
