It doesn't work that way. :-) A linemode telnet session, such as putty or the CMS TELNET (LINEMODE command gives you, is a virtual 3215, not a tty. 1. You press a key, the key goes to the VM telnet server 2. If it wasn't the ENTER key (CRLF), the telnet server accumulates the keystroke. 3. If it was ENTER, an ATTN interrupt on the virtual 3215 console is given to the guest. 4. Guest reads the entire line all at once. (This is why you have that funny ^c thing.) What you are asking for is a way to telnet into VM and request a do-nothing "pipe" between the telnet server and a Linux guest's console input/output stream. Three inventions required: 1. The do-nothing pipe. 2. A virtual ASCII system console that can operate without benefit of the real integrated ASCII (ATTACH SYSASCII). 3. A telnet server solicitor screen that allows you to select (or exits to pre-select) whether you want 3215 or TTY access to the guest.
