Activate ARF

Define an ARF terminal to use the ARF feature. You define an ARF terminal in the initialization file with GROUP, LINE, TERM, and STATIONS statements. The rules for these statements are as follows:

• The ARF GROUP statement requires a DEVICE=TRXDV.
• The ARF LINE statement requires that the BUFSIZE is 1024.
• The ARF TERM statement requires that the NLINE is 1.
• The ARF TERM statement requires that the LINLEN is 80.
• The TRXDV GROUP and LINE statements require that you include OPEN=YES.

The following example contains these statements:

GROUP,NAME=TRXGRP,DEVICE=TRXDV,LNAME=TRXLN,OPEN=YES
LINE,NAME=TRXLN,BUFSIZE=1024,TNAME=TRXT1,OPEN=YES 
TERM,NAME=TRXT1,DEVICE=TRXDV,NLINE=1,LINLEN=80
GROUP,NAME=TRXGRP2,DEVICE=TRXDV,LNAME=TRXLN2,OPEN=YES
LINE,NAME=TRXLN2,BUFSIZE=1024,TNAME=TRXT2,OPEN=YES 
TERM,NAME=TRXT2,DEVICE=TRXDV,NLINE=1,LINLEN=80
.......
STATIONS,TRMID=TRXT1,STANIDS=(TRX)
STATIONS,TRMID=TRXT2,STANIDS=(TRX2)

Update the initialization file RESTART statement with ARF=YES to use ARF.

Note: Consider increasing the region size that CA7ONL uses.

Verify that you have at least two TRXDV terminals defined.

Business Value:

An ARF terminal is required to issue some ARF responses.
