Re: Serial port Full Duplex or Half duplex?
Hi, Best look at Full Duplex and what it means. I think either could be a more appropriate answer. Depending on the device connecting to the serial port. Most devices you connect to a V.35 interface will indeed run at full duplex. Dulpex is not an ethernet thing but a comms thing that allows a connection to transmit on one cct and receive on another. It might use some form of modulation to separate one cct from another or could use a 4 wire connection as in ethernet as long as both circuits are separated.

Re: Serial port Full Duplex or Half duplex?
Ok Ok- ya got me... Of course V.35, RS-232, RS-449, Multimode, etc., etc. are used to support Full Duplex transmissions. Maybe it was BSMCN on the brain.

Re: Serial port Full Duplex or Half duplex?
Kiran, It depends on the protocol that you run over the serial interface. By default, synchronous serial interfaces operate in full-duplex mode . However, the usage of certain protocols changes that default to half-duplex. More info here: http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/12cgcr/inter_c/icserint.htm Keep in mind that the V.35 interface is relatively low speed (up to 48Kbps) and is recommended for use with packet networks rather than cell-switched networks (Frame-Relay, SMDS rather than ATM) so checking out he HSSI info won't do you much good.

My understanding is that serial is full duplex. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Kiran Kumar M Sent: Thursday, March 08, 2001 1:57 PM To: [EMAIL PROTECTED] Subject: Serial port Full Duplex or Half duplex?
