Presuming we are able to get any documentation out of any of these vendors; so far USB serial ports have been one of the worst things to enquire about. > I guess in the Windows world > they must provide 16550-virtualisation software, or else everyone's copy of > Telix or TeraTerm won't work.

If it's running in a DOS box, then it uses the 16550 virtualisation services that Windows offers, which layers over the COM driver or workalike. Basically, the same way that OS/2 does it. -- \\ The mind's the standard \\ Mike Smith \\ of the man. \\ msm...@freebsd.org \\ -- Joseph Merrick \\ msm...@cdrom.com To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-hackers" in the body of the message
