Chapter 6, IBASIC Controller
Interfacing to the IBASIC Controller using Serial Ports
Receive and Transmit Pacing
When receiving characters into the
microprocessor responds to each entry and no buffering is required. Therefore,
when using your PC or terminal to send characters to the
Line
When sending data through the Test Set's Serial Port to external devices like
printers which may have small input buffers, it is important to set
Xon/Xoff
when the printer's buffer is full and then start it again when the printer is ready.
The Test Set has a Serial Port input buffer length of 2000 characters. Buffer size
becomes important when IBASIC programs expect to receive large amounts of
data through the Serial Port with a single ENTER statement.
