Hello Craig

re: VT-MGR vs. Telnet

My feed back on this is:

http://raven.utc.edu/cgi-bin/WA.EXE?A2=ind0107C&L=hp3000-l&P=R5296

By the nature of the Telnet protocol standard, the single character
input and echo is high overhead on the network and the host.  The
NS-VT HP proprietary protocol is low overhead as all reads and
writes are blocked and result in fewer interrupts to the CPU.  The
NS-VT protocol is the more efficient protocol on both the network
traffic volume and host performance.

HP CSY has put significant effort into the HP-e3K Telnet to improve
it's performance, especially in the area of character echo which
is performed at the TCP layer rather than the Telnet layer.

A product called QCTERM also takes advantage of new functionality
added to the HP Telnet "advanced telnet" which supports local echo
to significantly improve telnet performance.

As I have said time and time again... to get the best Telnet
operation, make sure you install the current General Release Telnet
"PTD", NS-Transport "NST" and Internet Services "INT" patches.

I hope this helps.
