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 op en TELCOM on the Tandy 20 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.
