I found this message in my mailbox and I think it's a good idea to post it not only in comp.sys.hp48 but also here.

Subject: RS232 Homebrew for interface from RS232 to Ham Radio
Date: Thu, 9 Nov 2006 12:08:04 -0500I do not post to this group yet. I saw discussion about HP50 signal from RS232.
I built this interface and it works both ways. Many such as this are available already commercially or to build.
Please post to the HP group this information.
Also, I use eCom Station and before OS/2 since 1992.
