I have normally noticed that those who have problems autobauding from VMS do not
realize that they must type the carriage returns  s l o w l y ! !

I have told users to wait 2 seconds between carriage returns.  It takes awhile
for VMS to respond and change the baud rate on the DZ.  If the machine is
heavily loaded, one may need to wait longer.  1800 is the worst case
with 2400 being the second worse case.  I think that if properly
handled by a user, VMS will autobaud 2400 in 2 or 3 carriage returns.
Typing them too fast however will result in VMS thinking that the
response came after the DZ was switched to a new speed when in fact it
came either before or during the switch.

This is not fido, type the carriage returns slowly.

  =-=- This note is in response to yours which follows -=-=

We've got a number of ports defined as /AUTOBAUD/PERM connected to our
dataswitch here.  Normally 1 or 2 CRs is sufficient for the AUTOBAUD to
determine the baud rate and bring up the login prompt.

...except at 2400 baud.  At that speed, people generally need to type
a lot (10 or more) CRs.  Sometimes even 50 isnt sufficient.
A known problem?  Any workarounds?

Configuration:  11/780, DZ-11 ports, VMS 4.2.
