FDEVICECONTROL
This control directive is incompatible with the Escape
Sequence Read Termination control directive
(parm1 = 68). If both are enabled, the second
FDEVICECONTROL will return an error.
A positive value in buffer indicates the inter-byte
timer value in tenths (.1) of a second. That is, a value of
10 in buffer sets the inter-byte timer to expire in
1 second. If buffer is 0, the inter-byte timer is
deactivated.
If this directive is issued against a terminal connected
via PAD or DTC Telnet, this call will return a CCE
condition code, but the device control action will not
occur. This directive is not supported for VT
connections from an MPE V or HP-UX local client and
will return an error if used. Also, this directive is
supported for VT connections to an MPE/iX host or PC
running appropriate software only.
66 Define multiple type 2 EOR characters (AEOR).
This directive specifies up to 16 Alternate End of
Record characters. The buffer argument is a byte
array containing up to 16 characters. The following
characters may not be used as AEOR characters:
[CTRL]@ NUL
[CTRL]Q XON
[CTRL]S XOFF
[CTRL]Y the Subsystem break by default
The characters shown below should not be used as
AEOR characters because they may yield unpredictable
results:
[Return] carriage return
[CTRL]J line feed
[CTRL]X cancel line character by default
[CTRL]H backspace by default
[DC2] block mode alert character by default
[ESC] escape
The length argument contains the length of the array.
If buffer contains 0s or if length is 0, all AEOR
characters are canceled.
