ERROR DESCRIPTION:
A linemode (VT100) client connects to the Telnet server. TSO is
entered as the target application. The 'HELP' command is entered
from the TSO READY prompt. The HELP response, however, is
garbled. Translation of EBCDIC newlines (x'15') into the ASCII
string x'0D0A' does not always occur. If DEBUG DETAIL is
specified in the Telnet profile then the following message
will also be produced:

EZZ6035I TN3270 DEBUG CONN DETAIL 755
IP..PORT: ::FFFF:nn.nn.nn.nn..nnnn
CONN: nnnnnnnn LU: luname MOD: EZBTPLMT
RCODE: nnnn-00 Return code explanation not available.
PARM1: 00000000 PARM2: 00000000 PARM3: 00000000

Note: The RCODE will contain a random value.


LOCAL FIX:
Connect to the Telnet server with either a TN3270 or TN3270E
type client
