 I wasn't ignoring anyone here, but was on vacation.
I pinged the MPE host from my home pc using a cable modem and linksys router
and received packet times of about 20 ms.
I then tried it from my air card and experienced packet times of 500 to
1000ms.

That's quite a difference!
How does one go about getting advanced telnet?

I'm not quite sure what you mean by changing these settings:
Path:  NETXPORT.GPROT.TCP
[1  ]     Retransmission Interval Lower Bound (Secs)
[360  ]   Maximum Time to Wait For Remote Response (Sec)
[2  ]     Initial Retransmission Interval (Secs)
[8  ]     Maximum Retransmissions per Packet

I do have HP support for the MPE box. Is this something they would help me
with?

Thanks for all the responses.
