1996.0. "serial port, 115 kbps ?" by ZPOVC::POHING () Thu Jun 05 1997 07:56

    Hi,
    
    could someone pls help me with the serial port capacity on an
    alphastation & also the newly announced DPWS au series ?
    
    Could we meet maximum of 115 kbps per serial port ?
    
    And where could such info be obtained ?
    
    Thanxs.

	Re .0, i can only speak from practical experience - not from documentation since i have not looked it up - that we can run the serial ports on the recent Alpha models up to 115 Kbps. This was done via a null-modem cable for kernel debugging. Whether this is true for modem cables, i really cannot tell. --svb PS: that includes the XL 366, DPW a-series, and APC.
1996.2	just like a PC	WRKSYS::SCHUMANN		`Thu Jun 05 1997 21:03`	6
	All our workstation platforms use 82550 compatible serial ports capable of 115 kbps. Operating system support may vary. Keep your cable short to avoid trouble. 3 meters (10 feet) should not be a problem. --RS

	See note 66 in this conference for an old list of supported BAUD rates on an AlphaStation running various operating systems. That list hasn't been officially blessed, but it's probably a good start. Support should only have gotten better since then (about three years ago). -- Kenny House
1996.4	Synch Link?	XDELTA::HOFFMAN	Steve, OpenVMS Engineering	`Fri Jun 06 1997 11:12`	9
	Personally, I'd look at another way to connect these widgets. (The programs that seem to need to use the fastest asychronous serial line speeds traditionally never seem quite reliable, and I've spent more than a few hours chasing communications glitches.) Can you use a "real" network link for whatever the project is?
