Hi,

I am using a ZyXEL 1496E+ as a dial-in modem into my Unix box. It took me
quite a while, until people were able to log in, because the getty on my
Unix machine (NeXT) is a bit brain dead (it can't detect the baud rate
automatically). So I had to try all available baud rates until finally
38400 worked fine.

But how come the ZyXEL initiates the communication with 38400 ? I never
told it to do so and I don't know how to, either. I know about the 
AT&B0 setting, but that only locks the DTE rate and does not set it.
And I also cannot set the register S20 manually !

Does anybody know how to set the DTE rate for incoming calls ?

Or is there a better getty for the NeXT ?


Thanks for any info, Ernst.

	Getty is fine, this is what needs to be done:

	- Bit 3 of s38 should be set to 1 (i.e., ats38=8)
	- s18 should be set to the "getty/dte" speed you want to match
	  (note: there are other values for different speeds)
		2:	38400
		3:	19200
		7:	9600

	Another useful setting is s40=1 (to disable throughtput averaging)

	Make sure you "ATW0" and "ATZ0" to make these changes permanent!
