Programming for PAD, DTC Telnet, Telnet/iX Server, and VT Devices
PAD Access to MPE/iX Systems
FDEVICECONTROL parm1 values, with 192 specified as the
controlcode, will return a CCE condition code but have no effect on
the operation of the device or the transmission of data:
parm1 Action
1 Specify terminal type or printer type file
3 Set line speed
9, 11 Enable/disable parity checking
10, 12 Set parity type
14 Set line deletion response
26 Enable/disable XON/XOFF flow control
27 Set XOFF timer value
29 Define block mode alert character
30 Define block mode trigger character
51 Set typeahead mode
55 Select backspace response action
56 Specify data bits per character
60 Flush typeahead buffer
61 Bypass typeahead buffer
62 Set quiesce I/O
63 Set single echo typeahead mode
64 Ignore parity error on input mode
65 Set inter-byte timer
66 Define multiple type 2 EOR characters (AEOR)
67 Delete (DEL) to backspace (BS) mapping
68 Enable/disable escape sequence read termination
69 Enable/disable suppress echo of read termination
characters
73 Set FCLOSE timeout value
FDEVICECONTROL also verifies that a terminal is configured as a
PAD device. A parm1 value of 28 (controlcode 192) returns a value
corresponding to the type of block mode supported by the driver. A
value of 15 is returned by this call when the device is a PAD terminal
supporting (VPLUS) page block mode.
