4.3.2 OPMODE Response
The computer can use the OPMODE command to interrogate the PK-232 for information
on its current operating mode. The PK-232 sends one of the following responses:
Packet:
SOH $4F O P P A ETB
Morse:
SOH $4F O P M O x y z ETB
Baudot:
SOH $4F O P B A x ETB
ASCII:
SOH $4F O P A S x ETB
AMTOR Standby
SOH $4F O P A M $30 x ETB
ARQ:
SOH $4F O P A C v x ETB
ARQ Listen:
SOH $4F O P A L v R ETB
FEC:
SOH $4F O P F E v x ETB
SELFEC:
SOH $4F O P S E v x ETB
FAX:
SOH $4F O P F A v x ETB
where
v
= $30 if Standby
x
= S if transmit
$31 if Phasing R if receive
$32 if Change-over
$33 if Idle
$34 if Traffic
$35 if Error
$36 if RQ
$37 if Sync
yz
= present receive Morse code speed in words per minute
4.3.3 Link Status Request Response
Use the CONNECT command to query the link state of channel x:
SOH $4x C O ETB
The PK-232 response is:
SOH $4x C O
a b c d e
path ETB
where a, b, c, d and e are values $0-$F, ORed with $30:
a
= the link state -1, e.g., S05 is sent as $34
b
= $31 if the link is AX.25 L2 version 2, $30 if pre-v2
c
= the number of outstanding (unacknowledged) packets
d
= the number of retries done at this time
e
= $31 if CONPERMed, $30 otherwise
path = the callsign of the connects, followed by the digipeater callsigns
4.3.4 Callsign Formats
Examples of the callsign format are:
WA2DFI
W6CUS-1 via K6LLK, WD6CMU-1
