You have a flow control problem.
Check your terminal and terminal line to see what the flow control is. It can be hardware (DTR/DSR) flow control between the real hardware, but probably also needs to support software (XON/XOFF) between the simulated VAX and terminal. Dave From: [email protected] [mailto:[email protected]] On Behalf Of Nathan Cutler Sent: Tuesday, October 19, 2010 11:58 AM To: [email protected] Subject: EXTERNAL:[Simh] SimH + real terminal 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). 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.) 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. Changing the terminal speed and parity settings makes no difference. (But these have no meaning for a telnet session anyway, right?) Thanks in advance for any help in getting to the bottom of this. Please note: telnet sessions to the VAX originating from the Linux console or X session work just fine. This problem *only* occurs when I (1) log on to the Linux box from the serial terminal and then (2) telnet to the VAX. Any ideas will be greatly appreciated. Nathan
