The next 32 words are determined by the n value.
If n = 30, the Terminal Installation Parameters from NVM are sent.
If n = 31-36, the Mode Installation Parameters from NVM are sent.
If n = 37, the Active Mode Parameters from RAM are sent.
For n = 30, the Terminal Installation Parameters are sent as follows:
• Word 5 - See F2, 1 through 4, of Terminal Installation Parameters

Host Select Bidirectional Port
In CYBER mode, the host can select and send or receive informa-tion to either Port A or Port B of the opinforma-tional bidirecinforma-tional RS-232-C ports. The parameter bits for both ports must be set up before entering CYBER mode. The host must make certain that the transmit buffer is empty by ensuring X-On is active. When the terminal receives the host select bidirectional port sequence, it will interpret the next code (port and word size) as follows:
2 6 25 24 2 3 22 21 2°
I
0 = PORT A
V V V 1 = PORT B
X X X 2F - Default to Port B X = Bit value is irrelevant
Ports A and B have no parameters to select word size. The
default word size is 7 bits. The terminal will return an ACK to the host to indicate end of terminal data. The keyboard will be locked. DTR, RTS and CO will be sent to the selected port. At this time all data received from the host will be sent to the selected port and will not be acted upon by the display. As data
is received from the port, it is placed into the corom output buffer to be sent to the host. The standard host communication protocol is used to send the data as if it came from the keyboard
(Full/Half duplex, Constant/Switched RTS, Data Only).
If an RS is received from the host, i t is not sent to the port.
The next code is examined as follows.
• If it is an RS, a single RS will be sent to the port.
This allows the host to send an RS to the port.
e If it is a DC2, the bidirectional port will be deselected and the host interface will be returned to the parameter setting for word size and parity.
• If i t is anything except the DC2, the code will be sent to the port and the previous RS ignored.
• If a parity error is received from the host, a 7F is sent to the port.

X-Off/X-On
• Receiving X-OFF/X-ON - Transmit off/Transmit on (X-Off/
X-On) is supported by large CYBER mode. Each operating mode is defined in the following text.
• Character mode - When the X-Off is received from the host, all codes being sent to the host will be placed in the corom output buffer until the buffer becomes full. At this time, the keyboard is locked. When the X-On is received, the buffer will send and the keyboard unlocked.
• Block mode - When the X-Off is received from the host, no information will be sent to the host. Keyboard entry is still allowed. If a send function is initiated, the comm output buffer will be filled and no other operations will be performed until the X-On is received. When X-On is received, transmission will continue. The keyboard will remain locked. until cleared by the completion of the block send.
• Bidirection Port - When the bidirectional port is
selected, X-On must be active. In large CYBER mode, the X-ON and X-OFF can be placed anywhere in the data stream.
• Sending X-OFF/X-ON - This feature is supported in both large and small CYBER modes. The terminal has a receive buffer of 992 characters. If this buffer ever reaches 768 characters, the X-OFF will be sent to the host and the X-ON sent when the count goes down to 256.
Write New Mode Parameters
The host can temporarily override the CYBER mode installation parameters by changing them in the active RAM table.
NOTE
The host cannot change the Nonvola-tile Memory (NVM) table.
When CYBER mode receives the write new mode parameter command, it will input up to 32 codes and replace the active mode parameter words with them. The 32 words correspond to the 32 groups which are contained in the Mode Installation Parameters section. The
32 codes are received in the following format.
