Running with a locked speed to the local DTE is much nicer. But you obviously do need a working flow control to use this(*). If your serial port and/or drivers are broken, indeed, don't try to lock the interface. A couple of years back, broken handshaking seemed to be the rule rather than the exception, so it's no wonder both Telebit and SCO recommend running at a matching speed rather than locking it down. Saying "don't do it" as a blanket statement seems an unfair generalization. Is there some point I'm missing? (*) Unless you are running nothing but uucico to other PEP modems, in which case you can probably run without any flow control. -- Chip Rosenthal Unicom Systems Development, 512-482-8260 Our motto is: We never say, "But it works with DOS."
