## Serial Terminal Implementation

For those who wish to connect two computers, running OS-9, together using the serial port, redirection of the input or output paths is possible using the following modifier at the end of a command line:

    >/T1 - for an output path

    </T1 - for an input path

To pass a file of data between the two computers, one must be configured for input from the serial port and the other configured for output:

Computer 1, `BUILD TEXT </T1` - input to port

Computer 2, `BUILD <TEXT /T1` - output to port

Using the above example, the text file on computer 2 will be transferred to a file called TEXT on computer 1.

When the command line is entered on computer 1, the system will reply with a question mark and wait for information from the serial port. The command line on computer 2 will send data to the now waiting computer 1. A string of question marks will now be seen, this is the number of lines sent and recieved by the respective computers.

To create a log-off sequence after such a transfer, use the DISPLAY command as follows:

Computer 1, `BUILD <TEXT /T1 ; DISPLAY 0A 0D >/T1`
