Solaris

I am using ReflectionX on a windows PC to run an application on a Solaris box. The application uses the serial port and expects a definition like: /dev/ttyb
Is there a way to use the PC serial port through ReflectionX?
PC is running Windows-XP
Solaris Box is:
Sun Microsystems sun4u UltraAX-MP+ WorkServer (4 X UltraSPARC-II 480MHz)
SunOS 'hostname' 5.8 Generic_117350-39 sun4u sparc SUNW,UltraAX-MP

reflectionx is an X server, not an operating system. It has little to no control over your computer or theirs, it just pops up windows according to network sockets and data. It can't open and forward devices on command -- and if it did, that'd be a pretty big security problem.

Depending on how the application uses the serial port there may be some solutions available. I think any of them would involve running an application on your local machine to open the serial port and forward it over a network socket, and another on the remote machine to open that network socket and forward it to a local pty which you'd feed into your application.
