PK-232 TECHNICAL MANUAL CHAPTER 4 – HOST MODE AND SPECIAL APPLICATIONS
PK232TM Rev. A 5/87 4-6 Page 23
NOTE: Channel 'x' (0-9) refers to the Packet multi-connect channel that would be available
in verbose (human) mode by using the CSWITCH character. Only channel 0 is used
in all communications mode other than Packet mode.
The PK-232's response structure is:
SOH $4F
a b c
ETB
where
a
and
b
are the two-letter host command received from the computer, and
c
is:
$00 acknowledge, no error
$01 bad
$02 too many
$03 not enough
$04 too long
$05 range
$06 callsign
$07 unknown command
$08 VIA
$09 not while connected
$0A need MYCALL
$0B need MYSELCAL
$0C already connected
$0D not while disconnected
$0E different connects
$0F too many packets outstanding
$10 clock not set
$11 need ALL/NONE/YES/NO
$15 not in this mode
Other errors are: SOH $5F X X W ETB bad block
SOH $5F X X Y ETB bad CTL in block
4.3.1 Responses to Interrogation or Querry Commands
Responses to query commands consist of the following block:
SOH $4F a b (value) ETB
where the value is:
for a switch: Y or N
for a BEACON or PACTIME: E or A, space, and a number
for CONMODE:
C or T
for all other commands: the same as in the verbose mode, except for CON-
NECT, which is discussed in this chapter.
For example, to read the state of MRPT, send:
SOH $4F M R ETB
The reply should be:
SOH $4F M R Y ETB
