TI-83 Virtual Serial Port Testing

In preperation for a possible upcoming project, here is a tutorial for setting up a Windows XP machine with virtual serial ports for easy development. Three programs were used, HyperTerminal (comes with Windows), VTI 2.5(Virtual TI), and Virtual Serial Ports Driver XP 5.1.

VTI 2.5: http://www.ticalc.org/pub/win/vti.zip (FREE)
Virtual Serial Ports Driver XP 5.1: http://www.download.com/Eltima-Virtual-Serial-Ports-Driver-XP/3000-2070_4-10632957.html (14 day trial)

On the calculator, Telnet 83 was used along with ASHELL. Telnet 83 is available here: http://www.ticalc.org/archives/files/fileinfo/71/7116.html

• First, VSPD XP 5.1 was started and a virtual serial port pair was added to the system, (COM4 and COM5 in my case).
• Next, HyperTerminal was started and a new connection of 9600 baud, 8 data bits, 1 stop bit, no flow control was created, on one of the virtual COM ports.
• VTI was executed and ASHELL as well as Telnet 83 were loaded in (right click...send file to VTI)
• Before running ASHELL in VTI, Enable Cable Link...Gray Link was selected (right click) on one of the virtual COM ports previously setup in VSPD XP 5.1.
• Next ASHELL was executed, then Telnet 83, typing in Hyperterminal should display in VTI, and typing in VTI should display in HyperTerminal.

Below is a picture of the setup, it is large, so just follow the link to a new page:
