Good stuff. It doesn't mention PPP or SLIP, which I wouldn't think that it would. It does mention using USB to connect to a networking device and talks about sending Ethernet-encapsulated frames to the device. These frames include everything from the Ethernet Destination Address through the end of data, but not the CRC. The connected networking device must do the CRC. It also talks about sending ATM and ISDN data over USB. Interesting. _______________________________ Priscilla Oppenheimer www.troubleshootingnetworks.com www.priscilla.com > > > cheers, > mark. > > -----Original Message----- > From: Priscilla Oppenheimer [mailto:nobody@;groupstudy.com] > Sent: Wednesday, 6 November 2002 7:48 AM > To: [EMAIL PROTECTED] > Subject: RE: build tcp/ip on PC serial port [7:56885] > > > It's risky to bring up this subject again ;-), but the fact > that you can > configure HyperTermianl to Telnet over the serial port proves > that > TCP/IP > over serial does work.
