50g

I use an hp48sx (serial) communication for working with remote terminal units such as data acquisition devices using the modbus protocol, and others.  I use it on a daily basis, and have been very pleased with the small size and programmability features.  I would very much like to do the same with the hp50g, and take advantage of its larger screen size and enhanced processing power.  Now if I could just lay my hands on that darn cable!
