communication
The Tandy 200 has a db25 serial port on the back. Communication is through the TELCOM program in ROM. Open TELCOM. in the top left corner there is a string in the form of 88N1ENI,0
There could be something else there, but for a 9600BAUD 8n1 communication with xon/xoff and crlf conversion this is the good string. the string can be set by pressing F3:Stat and entering the right string behind it:
Stat 88N1ENI,0
If you prefer a faster speed: 98N1ENI,0 changes it to 19200, the max for this serial port.
To send a file from a pc to the Tandy 200 in linux, set the serial port with stty:
stty -F /dev/ttyS0 9600 ixoff
First open TELCOM on the Tandy 200 and push F4:Term to open a connection. Then push F2:Down to initiate a file download and enter a filename in a 5.2 scheme like text1.do (.do is to make it a textfile for the Tandy editor) and send a file with
$ cat file.txt > dev/ttyS0
during the download Down will be visible in reverse. After finishing press F2:Down again to finish the transfer.
Press F8:Bye to disconnect and confirm with y (enter). To return to the main menu, press F8:Menu. You should see the downloaded textfile in the menu.
To upload a file from the Tandy 200 to the host computer, use the TELCOM menu option F3:Up. TELCOM will ask you the filename (text1.do) and then the Width to insert automatic crlf after the entered chars (1-132). Type the wanted chars (80?) and before pressing Enter, open a file on the pc to write to:
$ cat /dev/ttyS0 > textfile1.txt
The file should be transmitted after pressing enter on the Tandy 200. After transmission has finished, press ctrl-c on the pc to stop the cat process.
