PCSERVER has been developed by Luigi Rizzo (luigi@iet.unipi.it),

It allows MSDOS-hosted Transputers to be completely controlled from a
networked machine. For each link adapter installed on the MSDOS
machine, PCSERVER listens to a TCP port for incoming connections. A
server (e.g. iserver/afserver) running on a networked machine can then
connect to PCSERVER and completely control the Transputer. Modified
versions of afserver and iserver that talk to PCSERVER are available
for several Unix machines (SGI IRIS, microVAX/Ultrix, DECstation,
SPARCstation).

PCSERVER is a standalone program, built on top of NCSA Telnet
libraries. As a consequence, runs on virtually any network hardware
either through the internal drivers or a Packet driver.  A hard disk is
not required.

In order to run PCSERVER, a proper configuration file for NCSA Telnet
must be produced.  The configuration file must be present in the
current directory, under the name "config.tel", or its complete
pathname must be present in the DOS environment variable "CONFIG.TEL".

One or more link adapters can be present on the MSDOS machine, provided
they have different I/O address. PCSERVER assumes a B004-compatibvle
board, but does not use DMA or Interrupts. The program must be run as
follows:

	PCSERVER [addr1 [addr2 ... [addrN]...]

where addr1..addrN are the I/O addresses of the link adapters. As
default, pcserver assumes a single link adapter at address #150
