V29FastPOS detailed wave files
The following is a wave files that show a V29FastPOS SDLC transaction. It was captured with the program listed
above with a keep-alive loop.
V29 Calling Tone
Calling modem is receiving
and sends to the DTE:
“Connect Packet” :
<EM><0xBE><0x24><0x24><EM><B1>
Then the SNRM Packet:
<0x30><0x93><EM><0xB1>
RTS (not RTS*) signal
Answer Tone
(2225 Hz)
DTE sends the calling
modem a UA packet
to transmit:
<0x30>(0x73><EM><0xB1>
Rev. 0.9
Calling modem is receiving.
Sends a Tx abort to DTE:
<EM><0xB2>
Then the received RR packet:
<30><EM><0xA0><EM><B1>
DTE sends the calling modem
an RR packet to transmit:
<30><EM><0xA0><EM><B1>
Repeat
