Thank you for that link. I have been looking for "terminal emulators"
and I have found the PockeTerm

VT6 http://www.sparetimegizmos.com/Hardware/VT.htm and the $360 (ouch!)
NTI SERIMUX Terminal Converter
http://www.kvms.com/Product/SERIMUX-TERM.aspx. The MicroVGA seems like the lowest cost solution, I just need to add a bit of perf board, a header, a MAX231CPD and two (tantalum) caps. As a benefit, there's a spare pair of drivers for the second serial port. Soren, I understand why the E6xx integrated video is not useful because of the supervisory LPC processor, and you would have to implement a video BIOS. Have you considered using the supervisor MCU as the terminal emulator to generate the VGA video? It could pass through the serial data and only inject characters if a PS2 keyboard were used. Looking at the MicroVGA, we've come a long way from Don Lancaster's TV Typewriter (I still have the "Cookbook," dog eared, packed away in a box some where).

My firewall is also my GPS strat-1 NTP server, UPS monitor and DHCP server, among other services.

[...] Thanks- AndrewIf you only need VGA, mouse and KB to manage your system within a text console using a KVM, I suggest you take a look at http://www.microvga.com/ They produce a small and cheap (VGA + 2x PS/2 connectors) <-> (RS232) conversion module that could solve one of your problem.
