[HECnet] DECnet performance problems (on TOPS-10)

[Paul_Koning at Dell.com]

Rterm for RSTS is pretty simplistic.   It works essentially like telnet local echo line mode normally, but it detects a couple of state changes on the controlled terminal: if echo is disabled, the local echo is likewise disabled.   And if the terminal driver goes into any kind of mode where line mode no longer works right -- ODT, binary mode, TECO mode, etc. -- it switches to no echo character at a time mode.   So, for example, TECO works, but you can tell that it all of a sudden got slower.

Hmm. At least better than cterm... :-)
But how does it deal with things like XON/XOFF, ^O and stuff? Is that left to the client side to do however it want, so it don't neccesarily work the same as a local terminal to the RSTS/E system?

If I remember right, the answer is: on the sending host when in line mode, on the RSTS system when in character mode.   Character mode essentially puts the local end in binary mode.
