Kat,

Thanks for the reply & code snippet.  I think I'm missing something basic 
with this.
1) In your code, you quit when you receive a '13'.  Does '13' signify end 
of transmission?
2) Why do you drop the '10' character--won't that elminate returns?

For example, the IMAP command
A FIND ALL.MAILBOXES "*"
might return quite a few lines (however many mailboxes the user has), such 
as:
* MAILBOX INBOX
* MAILBOX Accounts
* MAILBOX ArcServe
* MAILBOX Cisco
* MAILBOX Corporate Time
* MAILBOX DNS_DHCP
* MAILBOX Euphoria
* MAILBOX Linux
* MAILBOX Novell
* MAILBOX PMDF
* MAILBOX Robots
* MAILBOX Verisign
* MAILBOX WASTEBASKET
* MAILBOX deadletter
a OK FIND ALL.MAILBOXES completed

Won't it be bad if I delete out all of the \n characters?  Isn't a '13' and 
a \n sent at the end of every line?
Or more simply, how do I know how much data came back, and when I can stop 
looping for it?

Thanks,
Ted

It's a little time consuming to run, but it's fast enough, and it took no 
time to write it. I use that
same function in the SMTP section (port25), and almost the same code in the 
irc client (any
port). Specifying one byte at a time is safest, it won't hang waiting for 
anything if the
connection is broken, but it's also the slowest if everything is working 
perfectly. I do not close
the port until after the logout in any of the cases:

-- sign off properly
SendToServer(sock_connect[2],"QUIT\r\n")
-- listen for +OK for a little while
-- close the port after +OK or timeout
-- clean up tcp4u
-- clean up this application
-- end

The gotcha in IMAP, as i understand RFC 1203, is that the client-server can 
change the
command/handshake eol terminator string from crlf to whatever they want. I 
tried to look up the
latest data at www.imap.org but somebody broke the internet here and i 
can't reach many
websites since about midnight.
