How hard? Not sure how to measure that. :) Right now, we load up all of the env.XXX variables when the emulator starts, and assume them to be valid variables for the AS/400 to receive. When the AS/400 requests "NEW_ENVIRON" (see RFC 1572), we simply dump all of these variables... we pay no special attention to DEVNAME or any other variable, just dump em all... (That's not the "correct" way to handle it, but it hasn't caused problems yet. It's listed as a bug in the BUGS file in the distribution) If you wanted to make it do "device name collision processing" (as it's called in RFC2877) you'd need to change this behavior to actually look at which variables the AS/400 is requesting, and only sending those. Then, keep track of the state of the DEVNAME variable, if you get back another request for it after the first one, the device is in use, and you need to try again with a different value for DEVNAME... This would repeat until you found an available name, or you sent the AS/400 the same device twice in a row... once it gets the same device twice, it gives up :) (which is what happens now, except that we don't just send DEVNAME, we send everything...) See telnetstr.c, sslstream.c and RFC 2877... On Tue, 22 Jan 2002, Sean Porterfield wrote: > > Anyone have any idea how hard it would be to allow other dynamic naming from > tn5250?
