[HECnet] Who's emulating?

The async DDCMP driver is a whole new driver, and it depends on the terminal driver structure that exists in the later versions of RSTS. I don't remember when that was put in place, but I'm pretty sure it wasn't there in V8.0. I did the original work for RSTS V9.6, but that was just a private prototype. paul -----Original Message----- From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of Mark Abene Sent: Thursday, August 20, 2009 6:05 PM To: hecnet at Update.UU.SE Subject: Re: [HECnet] Who's emulating? Unfortunately, given my preference to using RSTS/E v8, I must use DECnet/E v2.0. Those DECnet drivers only support a DMC or DMR device (seen as "XM" in RSTS), or a DMP or DMV device (seen as "XD" in RSTS). Based on what you're saying, the patch would not solve this problem?

Or rather, the terminal driver contains an implementation of the DDCMP protocol. So it can talk to async DDCMP devices -- just as RSX did for years. Until V10, DECnet/E only did DMC/DMR type DDCMP devices. On a Pro, which has a USART (not UART) console port, it even speaks sync DDCMP if you want so it can talk to a DMC or DMR (and that works, I tested it). On other PDP-11s it will use any of the async lines and speak async DDCMP. paul
