this may work:
just use the lines going to rxd and txd os rs232(serial)
to your 80535 rxd txd serial port lines.

Equipment Monitor and Control / Manufacturer of Single Board Computers, Microcontrollers, PC/104 Modules and Microprocessor Training Systems. Custom and Semi-custom engineering services also available.
EMAC's SBC One Stop-Shop bridges the gap between SBC microcontrollers and PC compatible SBCs by offering both a wide assortment of Motorola, Siemens, Intel, and Zilog microcontrollers, and a comprehensive line of x86 SBCs.
The EMAC Compact Server-In-a-Box (SIB) runs Linux as its Operating System and as such retains all of the networking and communications capabilities one would expect of such an operating system. Right out of the box, the SIB is configured for Ethernet, serial IP, serial terminal, and raw serial connections. Other devices, including PPP modem links, may be added and configured by the user.
