    i have done it once before but I designed the boards and used discrete parts. However, this place http://www.laipac.com/ always advertises and their parts are very inexpensive. This would not connect to your RS232 directly as it uses 0-5V for signalling, you would need a MAX232 or similar inbetween. Alternatively, there are some premade systems that you just plug in, but they are usually expensive.
