I need make serial data from virtual serial ports available on a TCP/IP network.
For communications with hardware COM ports to send and receive serial data over a local network or the Internet.

POSIX machine (/dev/ttyS0) <--- TCP/IP ---> Windows machine COM1

Please help! I try use Sredird daemon - RFC 2217-compliant serial port redirector. But I need binary transmission... Sredird trans only known symbols.
Thank you very much!!!

dc

dc(4)							     Kernel Interfaces Manual							     dc(4)

Name
       dc - serial line/mouse/keyboard

Syntax
       device	 dc0  at ibus?	vector dcintr

Description
       The  serial line controller provides four ports, with modem control on two of the ports.  The DECstation 3100 and DECstation 2100 only pro-
       vide partial modem control.  The DECstation 5000 provides full modem control. The ports are used as follows:

       Port	 Usage
       0	 Graphics device keyboard at 4800 BPS
       1	 Mouse or tablet at 4800 BPS
       2	 Communications port 1 (w/modem control)/local terminal
       3	 Communications port 2 (w/modem control)/local terminal

       Each communication port from the serial line controller behaves as described in and can be set to run at any of 16 speeds.  For the  encod-
       ing, see

       When  a	graphics device is not being used as the system console, communications port 2 becomes the system console.  In this configuration,
       the port can only be used at 9600 BPS and no modem control is supported.

       The serial line driver operates in interrupt-per-character mode (all pending characters are flushed from the silo on each interrupt).

Restrictions
       Speed must be set to 9600 BPS on the console port and 4800 BPS on ports used by graphics devices.  The serial  line  driver  enforces  this
       restriction; that is, changing speeds with the command may not always work on these ports.
