Diagnostic Parameters and Commands
Using diagnostics-related DO commands
The next two lines show the MAX modem sending the first string. The second line shows that
a buffer needs to be allocated for sending the command out the WAN.
MODEMDRV: Answer String, Part 1 - AT&F0E0
MODEMDRV-3/1: _hdlcBufSentFnc: buffer = 2E12EAE0, status = SENT
Buffers are allocated for data being received from the WAN:
MODEMDRV-3/1: _hdlcBufRcvdFnc: data=2E13ADF0, len=8,
parseState[n,v]=[0,0], status= RCVD
MODEMDRV-3/1: _hdlcBufRcvdFnc: data=2E13BA20, len=5,
parseState[n,v]=[0,0], status= RCVD
The MAX modem receives OK from the calling modem:
MODEMDRV-3/1: data =OK
The same process is repeated for strings 2 and 3:
MODEMDRV-3/1: _processTimeout/DIAL_STR2
MODEMDRV: Answer String, Part 2 - AT&C1V0W1X4
MODEMDRV-3/1: _hdlcBufSentFnc: buffer = 2E12EAE0, status = SENT
MODEMDRV-3/1: _hdlcBufRcvdFnc: data=2E13C038, len=2,
parseState[n,v]=[0,0], status= RCVD
MODEMDRV-3/1: data = 0
MODEMDRV-3/1: _processTimeout/DIAL_STR3
MODEMDRV: Answer String, Part 3 -
AT%C3\N3S2=255S95=44S91=10+MS=11,1,300,33600A
Now, result codes are processed to clarify the characteristics of the connection. The MAX
modem sends a result code of 52, or CARRIER 14400, and the MAX modem receives the
same speed from the calling modem:
MODEMDRV-3/1: _hdlcBufSentFnc: buffer = 2E12EAE0, status = SENT
MODEMDRV-3/1: data = 5
MODEMDRV-3/1: _hdlcBufRcvdFnc: data=2E13ADF0, len=2,
parseState[n,v]=[5,0], status= RCVD
MODEMDRV-3/1: data = 2
MODEMDRV-3/1: decode= 52
Result codes 77 and 67 indicate that V.42 error correction and V.42bis error compression,
respectively, have been successfully negotiated.
MODEMDRV-3/1: _hdlcBufRcvdFnc: data=2E13B408, len=1,
parseState[n,v]=[2,0], status= RCVD
MODEMDRV-3/1: data = 7
MODEMDRV-3/1: _hdlcBufRcvdFnc: data=2E13BA20, len=8,
parseState[n,v]=[5,0], status= RCVD
19DEMDRV-3/1: data = 7
MODEMDRV-3/1: decode= 77
MODEMDRV-3/1: decode= 67
At this point the modem call is up, and the modem driver has completed its task. From here,
the call will be passed to Ethernet resources:
MODEMDRV-3/1: _processRcodeEvent/AWAITING RLSD, mType=5, RLSD=0
MODEMDRV-3/1: _processRlsdChange/AWAITING RLSD = 1
