listen( maxpend = 5 )

In the below line (from tcp.h), what is the maxpend?
Is it the limit of ports that can be configured to listen for a tcp connection?

"inline int listen( IPADDR4 addr, WORD port, BYTE maxpend = 5 )"

Thanks,
Tim Snelling

Arrows in the icons of files that I just added

Why are there arrows in the icons of the new .htm, and new .gif, that I just added to my project?
What do the arrows mean?
Apparently I did something wrong, how do I correct this?

Re: CB34EX JP23 / JP26 Description

Tom, another question,
If I'm doing RS-485 on both ports, the JP23/JP26 termination resistors only apply to the TSTRIP5 correct?
Are there no termination jumpers for RS-485 on the DB9?

Re: CB34EX JP23 / JP26 Description
