PROTOCOL CONVERTER MODEL A/S-4

6.11.1CHANGING INTERACTIVE APPLICATION OPTIONS

The change Application menu allows 8 operations as described below:

A. Exit - By entering the letter A the A/S-4 will return to the Main Menu.

B.XID - By entering a B the operator is able to change the A/S-4 SDLC control unit identifier. Only hexadecimal numbers are allowed to be entered for this selection, the first two digits are fixed at 01. The next character indicates what type of device the A/S-4 (7=3274, 8=3276, 0=3774, 1=3774P, 2=3771 and 3=3776/77).

C.PU Addr - To change the units physical unit address enter C. Only hexadecimal numbers are allowed to be entered for this selection; addresses x’00’-SSCP address and x’FF’-Global SDLC address can not be used.

D.SDLC Baud Rate - By entering a D the operator can select the baud rate at which the host will transmit and receive data from the A/S-4. This selection is only used when running SDLC over asynchronous modems or when the A/S-4 is supplying clocks to a front end processor. After entering the letter D the current baud rate will be displayed. To change it, enter the letter Y which will scroll pass each selectable baud rate, when the correct rate is displayed entering any key other than the Y will save the new baud rate.

NOTE

SDLC baud rate has no effect when running with synchronous modems.

E.XON/OFF - Entering an E allows the selecting of the DC1 (XON), DC3 (XOFF) protocol on the A/S-4’s terminal port. This protocol can be used; TO the unit or FROM the unit or in BOTH directions. To disable the XON/OFF protocol, select the option for OFF by the use of the letter Y, entering any key will save the selection. This protocol is used so the A/S-4 or the attached async device will not overflow each others buffers with data. If the A/S-4 has room to store only 20 characters from the VDU, the unit will drop it’s RTS signal (can be connected to pin 4, 5, 11, 19 or 20 of EIA connector) and send an XOFF character if option is set for FROM or BOTH. When the A/S-4 is sending data to the VDU, the VDU can stop the flow by dropping it’s signal connected to the A/S- 4’s CTS or by sending a XOFF character, if the A/S-4’s XON/XOFF option is set for TO or BOTH.

F.VDU LU Addr - The VDU LU address can be changed by entering the letter F. For this selection only hexadecimal numbers are allowed to be entered, from the range of X’01’ to X’FF’ but for most installations the address range of the specific type of control unit is as follows:

IBM* 3274 = X’02’-X’21’

IBM* 3276 = X’02’-X’09’

IBM* 3776 Model 3 and 4 = X’01’-’06’

NOTE

Do not set the VDU and PRT LU addresses to the same values.
