<p class=MsoNormal>I just got my hands on a "real" text terminal (the
kind with the amber CRT display). It's a CADO Systems C332 (emulates various VT
models). <br>
<br>
I connected the terminal to my Linux box's serial port and started a Linux
serial console on it. I have the terminal working flawlessly with Linux. (I can
use "vi" etc. on the Linux box.) <br>
<br>
However, when I take this a step further, and telnet into the SimH/VAX, a
problem appears. When the VAX sends just a few characters of output, everything
is fine. But when it sends a bunch of characters at once (e.g. when I do $ DIR,
or $ TYPE <long file>), I get the first couple lines OK but then it just
breaks up into nonsense. <br>
<br>
Changing the terminal speed and parity settings makes no difference. (But these
have no meaning for a telnet session anyway, right?) <br>
<br>
Thanks in advance for any help in getting to the bottom of this. <br>
<br>
Please note: telnet sessions to the VAX originating from the Linux console or X
session work just fine. This problem <span class=moz-txt-tag><b>*</b></span><b>only<span
class=moz-txt-tag>*</span></b> occurs when I (1) log on to the Linux box from
the serial terminal and then (2) telnet to the VAX. <br>
<br>
Any ideas will be greatly appreciated.<br>
<br>
Nathan <o:p></o:p></p>
