Configuring Pseudo TTY's (PTY's)

To enable network login access to the Call Server, either via putty or rlogin, you'll need to have some Pseudo TTY's.
It's recommended to build a few, say three, incase one locks up.

Configure a Pseudo TTY in LD 17 - ADAN: CTYP = PTY and USER = SCH MTC BUG

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.

    >ld 17
                  
    REQ  chg
    TYPE adan
    ADAN new tty 3
    CTYP pty
    PORT 1
    DNUM 03
    DES  ELAN
    FLOW 
    USER mtc bug sch
    TTYLOG 
    BANR 

    ADAN new tty 4
    CTYP pty
    PORT 2
    DNUM 04 
    DES  ELAN2
    FLOW 
    USER mtc bug sch
    TTYLOG 
    BANR 

    ADAN new tty 5
    CTYP pty
    PORT 3
    DNUM 05 
    DES  ELAN3
    FLOW 
    USER mtc bug sch
    TTYLOG 
    BANR 
    
    ADAN (press return twice to exit...)

Note: You cannot configure more than 16 TTY's (TTY 0 thru 15), including an (optional) History File (HST). If a HST file is one of 16 TTY files configured and a new TTY is defined, the HST file is deleted because the TTY has higher priority than HST.
