I want to use a program like this on a Tandy Model 100:
10 REM COM Port SetUp 9600 8N1???
20 PRINT "TRS-80 Model-100 is sending this out!"
30 GOTO 20
I need to know what line(s) to replace line 10 with?

I think you may need an expansion interface for the TRS-80. It came with a manual, too. Do you have such hardware included?– jonkSep 9, 2022 at 22:21

Hi, The Model 100 computer has a RS-232 port on the back, I just want BASIC to send the output from the program out the RS-232 port. No expansion ports should be needed.– wperkoSep 9, 2022 at 23:06

Ah. I did have one. But it was a very long time ago. I seem to recall getting an interface for it and it had a separate manual. My mistake, then. What do you have on the other end of the interface?– jonkSep 9, 2022 at 23:07

@wperko Please add the information what system that is about as part of the question.– RaffzahnSep 9, 2022 at 23:17

The BASIC is a rather straight Microsoft 8 bit variant, so just open COM as a file:
10 Open "COM:88N1" FOR OUTPUT AS 1
20 PRINT #1, "TRS-80 Model-100 is sending this out!"
30 GOTO 20
Values are:
- COM: select the serial port
- 8 selects 9600 Bd
- 8 is word length
- N for no parity
- 1 for a single stop bit
See page 125 of the Model 100 Owner's Manual for a description of all parameters, as well as page 165 for the open command.
A more in depth description and tutorial examples is provided in the Model 100 Basic Language Lab by Lesson #14 Using the COM Option starting at page 165.

6Hi, My Model 100 required "COM:88N1E" ... now with the "E" it runs ... thanks!– wperkoSep 10, 2022 at 0:33
