As much as I hate to be the bearer of bad tidings, I've seen some nasty behavior with Xyplex terminal servers. Specifically, they apparently use a simple TCP with a fixed retransmission timeout of 200-500 ms. As you might expect, such a small timeout doesn't work too well when you're trying to telnet across a WAN. It shouldn't be a problem when telnetting on a LAN though. I work for a vendor of multiprotocol routers for satellite links. We've had to put Xyplex on our black list of products that don't work over satellites, and we explicitly recommend to our customers that they look elsewhere for terminal servers. If there's a newer version out there that doesn't suffer from this problem, I'd like to know about. (Is anyone from Xyplex listening?) I'd be happy to arrange for a new interoperability test. If the new version works okay, we'll take Xyplex off our black list and I'll send an updated announcement to this newsgroup. --- Stephen Thomas (sat@tridom.com) AT&T Tridom (404-426-4261)
