In most ways, the link will resemble a normal modem connection. When a

key is typed on one terminal, the ASCII byte corresponding to that

character will be sent out the computer com port to the Vector. The Vector

will embed this character into the data it is sending, and the Vector on the

far end will extract this character from the incoming data. It will then send

the character to the other computer com port, and it will appear on the

other display. Of course, since the channel is full duplex, this exchange

may be happening in both directions simultaneously.

A few common options in terminal programs will ease communication:

a) Local echo  Engage this if you wish to see what you are typing on your

own display. The Vector cannot echo the characters you send back to your

display, only send them to the other end. You must configure your

communications program to do this.

b) Cr-> CR-LF  When you type a carriage return (enter key), the CR

character is all that is usually sent through the Vector data link. Your

program will likely interpret this correctly and send the cursor back to the

beginning of the same line. Your program can probably be set to interpret

the CR character as both a CR and LF (line feed) sending the cursor to the

beginning of the next line. Your program can also usually be altered to

send both characters when the enter key is pressed. Usually only one of

the above options is required.

c) Other options  The software setup of your communications program

may require additional parameters. Keep in mind that the Vector data

channel is simply a pipe. What bytes are sent and how they are

interpreted is completely dependent on the software being used and how

that software is configured.
