Kevin, I assume by "TN3270 TELNET" you are referring to the TN3270 Telnet Server as documented in Chapter 13 of the z/OS 1.7 CS IP Configuration Reference manual.[1].
Are there perhaps some undesirable characters present also with the text asking for the application name? I would expect so. It's evident from the text asking for a password that you are receiving a 3270 data stream - the initial "5", for example, is the Erase/Write command. The BIND image which you have presented to TSO has persuaded TSO that you are using programming/microcode capable of presenting a 3270 data stream rather than SNA character string (SCS) which is required for basic TELNET operation - also called "linemode". The BIND image is obtained from the content of the mode table entry under a particular mode name. The name of the mode table entry, the mode name, which is used by default - and there's almost no reason to change it - is INTERACT, the very first entry in the IBM-supplied mode table which is even more than a default mode table in that it is automatically considered to be concatenated after any customized mode table which is defined with the, in this case, APPL statements representing the secondary LU associated with the TELNET connection. In the statements which control the TN3270 Telnet Server in the CS IP PROFILE (or equivalent if the "stand-alone" version of the server is used), INTERACT is the mode name specified for use when the TN3270 client specifies that the "device type" LINEMODE. According to your post, your TN3270 client has specified LINEMODE and your NETSTAT output shows mode name INTERACT. The only conclusion I can reach is that your VTAM folk have managed to redefine the mode name INTERACT so that TSO imagines it can use a 3270 data stream when it receives the BIND image defined under mode name INTERACT. I suggest you get your "network guy", who I imagine is your "VTAM guy" ,and ask him to sort it out using, to be sure he sees the problem clearly, NetView Session Monitor trace data. If the solution is still not clear, please post again preferably with hexadecimal of the BIND request used for the TSO session which is easily obtained from NetView Session Monitor. Chris Mason [1] This deals with Tony Harminc's point about TN3270 not being appropriate for LINEMODE. I fell into this trap a little while back and was politely requested to go and look what the CS IP folk called their old TELNET server these days. ----- Original Message ----- From: "Klein, Kevin" <[EMAIL PROTECTED]> Newsgroups: bit.listserv.ibm-main To: <IBM-MAIN@BAMA.UA.EDU> Sent: Monday, 01 May, 2006 11:26 PM Subject: IBM TCPIP TELNET LINEMODE > We're doing a POC on a new product that requires a TN3270 TELNET connection to z/OS 1.7 in LINEMODE protocol.
