Configuring Pseudo TTY's (PTY's)
- Check that MULTI_USER is ON by printing OVLY (overlay) in LD 22, the default is OFF.
It is enabled in LD 17 - REQ: CHG, TYPE: OVLY. Enter down to MULTI_USER and type ON.
- To find out which TTY/PTY port you're logged in on, type WHO at the > prompt.
WHO will display the user name, port ID, and overlay loaded for each logged-in terminal.
- FORC xx Forces terminal xx to log off (when logged in with LAPW or a level 2 password).
Use this if you receive a OVL429-OVERLAY CONFLICT error during important maintenance.
Configure 3 PTY (TTY) ports:
Print the ADAN block in LD 22 to check what is available, we need to note the TTY and DNUM numbers:
>ld 22 REQ prt TYPE adan tty ADAN TTY 0 CTYP QSDI GRP DNUM 0 DES FLOW NO USER MTC OSN XSM YES TTYLOG 0 BANR YES ADAN TTY 1 CTYP QSDI GRP DNUM 1 DES FLOW NO USER MTC TRF SCH BUG OSN XSM NO TTYLOG 0 BANR YES ADAN TTY 2 CTYP QSDI GRP DNUM 2 DES FLOW NO USER MTC TRF SCH BUG OSN XSM NO TTYLOG 0 BANR YES
Configure the new PTY ports, starting at a vacant TTY number, incrementing TTY, PORT, and DNUM numbers as you go.
If you are building a 5.5 or newer system, delete the TTY's with CTYP QSDI (upto four), and rebuild them as PTY's. DNUM will automatically increment as you build them. The QSDI (Quad Serial Data) card is not longer supported, but the legacy TTY's still linger in the default customer database.
