The Generic option is an unsupported choice. It is provided to allow
users the option of attaching a printer of their own choice. 

Printer Speed (H)

Shows the speed of the printer interface.

Printer Data Bits (I)

Shows the number of bits in a byte over the printer interface.

Printer Stop Bits (J)

Shows the number of stop bits in a byte over the printer interface.

Printer Parity (K)

Shows the parity of each data byte over the printer interface.

Printer Flow Control (L)

Shows the flow control being used by the printer.

Go ahead on Buffer Empty (M)

Computers that send data in blocks use this option. After a Block has
been used up (i.e. the buffer is empty) the Telex Unit sends a Go Ahead
(SO) to the Host.

Printer Compulsory (R)

This  option  indicates  whether  the  presence  of  the  printer  overrides
Host  security  such  that  continued  acceptance  of  incoming  calls  is
permitted when the host computer is in fault condition.

Drop Carrier on Line Closed (S)

This option controls the state of the carrier presented to the telex line
under  a  Closed  Line  condition.  The  default  value  leaves  the  carrier
enabled in a Closed Line condition.

Automatic Reset (T)

The  default  value  for  this  option  means  that  a  soft  reset  command,
(ESC)  A,  is  required  to  put  the  unit  into  idle  state  from  a  power  up
state.  This is the normal operation of the telex unit when driven by
most applications. By enabling this option, the telex unit goes directly
on line without requiring a reset command.

Previous Line (X)

Used  when  in  prompted  mode  for  displaying  the  previous
configuration parameter.
