The BUFFERS show the current contents (in hexadecimal) of the Transmit
(TX) and Receive (RX) buffers contained in the operator interface. These
buffers are circular in nature. The Psh (push) and Pop values indicate the location
in the buffer where the next character will be loaded or unloaded respectively. If
the values are equal, then the buffer is empty. To aid in viewing the buffer
locations, the cursor keys can be used to highlight the buffer contents. The
current location of the cursor is shown in reverse video in the mid-right screen.

– control characters

– hexadecimal data.
