So there's going to be manufacturer-specific terminal/serial port drivers to talk to the serial ports on USB-attached laptop docking stations, like the Annex ethernet terminal server things? I guess in the Windows world they must provide 16550-virtualisation software, or else everyone's copy of Telix or TeraTerm won't work. Or the parallel ports vs parallel-port scanners. Or maybe these docking stations just won't work at all... -- Andrew To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
