debug packet xchange

[Ispa]

is there anyway to debug (printing log to external file or console) the packet exchange between the POL SRV and UO Client?

If you're using POL 096 or newer, there are built in text commands to POL .startlog and .stoplog. This works only on your char when you do it and it puts the log in POL/log/[acctname].log. If you're using POL 098 RC1 or newer, there is also a character priv plogany that you can set to yourself to allow you to target a character with .startlog and get this same log information from other characters. Be advised you should only do this for debugging purposes, many logs going at once can lag a shard severely.
