Let me add a little more detail
I'm compiling on solaris 8, gcc3.3 and running on solaris 8.
I don't know much about the communication between the device (SLC 500 PLC)
and the driver.
The driver is sending this. The second line is my understanding of the
data. cmd = [01] is an unprotected block read
[10] [02]{[01] [01] [01] [00] [01] [00] [00] [00] [5E]} [10]
[03] [FFFFFFE4] [29]
DLE STX {cmd dst src sts lsTns msTns lsAddr msAddr bytecount} DLE ETX
[checksum] [checksum]
And the response is (along with my understanding)
[10] [ 6] [10] [ 2] {[ 1] [ 1] [41] [10]} [10] [ 1] [ 0] [10] [ 3] [38]
[1f]
DLE STX DLE STX {dst src cmd sts } DLE [lsTns] [msTns] DLE ETX
[checksum] [checksum]
The response is being rejected because it doesn't contain the requested 94
bytes.
Any help appreciated
