How to send an ASCII file to a Model 100 via RS232C

Receiving an ASCII (plain text) file over the serial port is easy on a Model 100 and no special program is needed. Sending a file to the Model 100 is also fairly simple, but the instructions depend upon what type of computer you are using.

The rest of this page presumes you have already connected the two computers using an RS232C serial cable called a "null modem".

Side note: For binary (non-ASCII) files, you must use a special program, like TEENY.

Sending from a GNU/Linux UNIX box

• Use the sendtomodelt program, which is essentially a glorified cat foo > /dev/ttyUSB0.

Sending from any UNIX box, logged in with getty

Turn on Download in TELCOM, which starts a screen capture, and use cat foo on the UNIX host, where foo is the name of the file you want to transfer. Turn off Download when finished.

• Tip: To avoid having the command "cat foo" and the trailing prompt embedded in the file, you can do this:

  1. Type cat foo; read but do not press Enter.
  2. Turn on TELCOM's Download.
  3. Now press Enter.
  4. Wait for the file to finish transferring.
  5. Turn off Download.
  6. Hit Enter a final time to get back to the prompt.

• Tip: For large files, one can speed up transmission by disabling the Model 100's screen scrolling. Use echo -en "\eV" to turn off scrolling and echo -en "\eW" to turn it back on.

Sending from Apple MacOS UNIX

• The sendtomodelt program could work but it will need to be tested and ported.

Sending from another Model 100

• If sending a BASIC program: SAVE "COM:98N1ENN", A

  Side note or NEC users

  For the NEC PC-8201A, use SAVE "COM:9N81XN", A

• If sending a text file: use TELCOM's "Upload" function (F3 on Tandy portables).
