While doing review of it for fearless editor Ron second at the CHRONICLE.  I was able to convince  TELERAY  staff to implement a TYPE A HEAD. Feature!
They did so and terminal became mybyeinal of choice  for the rest of my HP 3000. Usage. See attached photo of nice letter they presented me with.

You're welcome.  I am a classic-3000 kind of guy, which means afterkludged type-ahead for me.

But, I had thought type-ahead was a feature on MPE XL and MPE/iX.

NS VT in the middle could complicate things a bit.  VT is basically a device for proxying MPE terminal I/O requests across the network, which means the VT client (in your case on FreeBSD) knows whether there is a read pending and can make decisions based on that about whether to buffer or discard received keyboard data.  

I used to work on the WIN/TCP for MPE/V TELNET server, which is in a similar role: it gets somewhat-pre-processed terminal I/O requests and makes decisions what to do with received keyboard data.  Being a classic-3000 kind of thing means it doesn’t know about type-ahead.
