I have already posted this to comp.sys.sun and comp.protocols.tcp-ip and comp.os.vms but I thought some one might have done somethin like this in the UNIX world... I am using a UNIX-PC connected to a VAX as a terminal, via a hardwire connection to a multiplexor, and then invoking telnet to log in to a SUN attached to a TCP/IP network linking everthing together. ( except my PC ) The problem I'm having is that while I can do file transfers via kermit to the VAX with no problem, I cannot pass data to the SUN in anything but the smallest amounts. cu's put and take seem to overrun the SUN's tty interface buffers, Kermit will simply not work, I cannot even get the files started and Xmodem/Zmodem will not work either. I suspect the problem to be in the telnet protocol's handling of data and packet sizes. I have tried setting binary and charmode on telnet to no avail. Has anyone done anything like this before and been successful? My objective is get uucp working between my machine and the remote SUN. If there is a good reference on the innards of Telnet between the VAX and the SUN, I would sure like to know about it. Please E-mail any help to me and I will try and summarize if there is a decent solution. Thanks in advance.

My Yes, I do something similar all the time: PC --> PACX --> VAX --> SUN --> SUN ... or PC--> Gandalf SMUX --> terminal server DEC 100 --> VAX --> SUN --> ... Kermit between the PC and the (very!) remote Sun works just fine for text files (binary a bit dubious but not really necessary) HOWEVER, we use DNI between the VMS VAX and the Sun, and rlogin to get to other Suns without DNI. Try rlogin instead of telnet ??. >Please E-mail any help to me and I will try and summarize if there is a >decent solution. Sorry, the return path is so tortuous I have to post it to the net. -- Stefan W. Mochnacki INTERNET - stefan@helios.physics.toronto.edu Astronomy, U.

I haven't tried this particular combination, but based on net recommendations when I find Kermits that don't wanna talk I try set parity even on each end and that usually works. -- Jim Rosenberg pitt Oglevee Computer Systems >--!amanue!oglvee!jr 151 Oglevee Lane cgh Connellsville, PA 15425 #include <disclaimer.h>
