1. Enter the pattern as pairs of hexadecimal characters separated by a single
blank as shown on the screen above.
It is possible to send an empty (null) data pattern; to do this, simply enter 'C',
then press SEND. This may be useful if you wish to send an empty message
consisting only of a header and a trailer.
2. Enter 'C' followed by SEND to check the data for valid hexadecimal
characters.
3. The investigation mode screen or the statistical counters screen is displayed,
depending on the option specified in the OPTIONS screen.

Notes:
1. You can return to the OPTIONS screen at any time by pressing PF3.
2. The IBM NCP and the Link Test Responder programs can both buffer a full
128 bytes. Other responders may be limited to less than 128 bytes; for
example, the Controller Load/Dump Program (CLDP)
is
limited to 32 bytes.
In this case, there
will
be· an INVALID DATA RECEIVED message if the
test message sent by the requester was longer than the limit.
