'O'

= Odd parity

 

'E'

= Even parity

protocol:

'M'

= Multipoint (default)

 

'F'

= None protocol

address:

'A'

= terminal address ID for Multipoint mode

 

 

(default)

 

Each MR350MKII has to be assigned a unique

 

communication address when it is used in a

 

Multipoint environment. The address is used by a

 

host or concentrator to perform polling functions.

 

Characters 'A'-'Y' and '0'-'6' are used for assigning an

 

address ID of each terminal.

timeout:

'02'

= polling timeout two cycle periods

(default).

'02'-'FF' in hex format.

The value of this setting is specified for the communication timeout. If the MR350MKII does not receive a response from the host system within the number of timeout cycle periods, the MR350MKII regards the communication as unsuccessful and the transmission is then aborted. If the timeout value is set to zero, no timeout check is performed by the MR350MKII.

2.5.Terminal Control Table (available for host port only)

The terminal control table is meaningful only if the MR350MKII operation switch is set to "terminal mode". All other operational modes ignore the terminal control table.

2.5.1.Type Definition

The terminal control table is defined by the following typedef TERM_CONFIG. There is only one instance of the TERM_CONFIG data structure:

typedef struct { char terminal_id[8];

/* terminal id */

BYTE

online;

 

BYTE

echo;

 

BYTE

autolf;

/* auto LF */

BYTE

mode;

 

BYTE

linepage; /* line or page block */

BYTE

lineterm;

/* line terminator */
