Subject: [TUHS] CR delay for VT05
Date: Mon, 20 Jul 2020 00:32:07 +0100 (BST) [thread overview]
Message-ID: <20200719233207.BB69D2D9E6DD@macaroni.inf.ed.ac.uk> (raw)
Looking at the 6th edition man page tty(2), I see
Carriage-return delay type 1 lasts about .08 seconds and is
suitable for the Terminet 300. Delay type 2 lasts about .16
seconds and is suitable for the VT05 and the TI 700. Delay
type 3 is unimplemented and is 0.
New-line delay type 1 is dependent on the current column and
is tuned for Teletype model 37's. Type 2 is useful for the
VT05 and is about .10 seconds. Type 3 is unimplemented and
is 0.
Why would the VT05 (a VDU) need a delay for carriage return?
I can just about imagine that it might need one for linefeed
if it shifted the characters in memory.
