The vt52 emulation mode of the 520ST leaves a bit to be desired, and I
have been able to improve things by using a different termcap file.
The following file sets my TERMCAP variable with the command
	source st.tc
under csh, or you can pull out the termcap entry and get it installed in
/etc/termcap:

setenv TERMCAP "st|520ST:al=\EL:am:bl=^G:bs:cd=\EJ:ce=\EK:ce=\EK:cl=\EE:cl=\EH\EJ:cm=\EY%+ %+ :co#80:cr=^M:dl=\EM:do=^J:ho=\EH:is=\Ee\Ev:kb=^H:kd=\EB:kl=\ED:kr=\EC:ku=\EA:le=^H:li#24:md=\EbB:me=\Eq\EbC:mr=\Ep:nd=\EC:nl=^J:pt:rc=\Ek:sc=\Ej:se=\EbC:so=\EbA:sr=\EI:ta=^I:ue=\EbC:up=\EA:us=\EbB:ve=\Ee:vi=\Ef:vs=\Ee:"

There are a couple of gimmicks, such as using colour for standout mode.

This is not perfect, and I have trouble with the last line on the screen
-- if anybody has improvements, plese post them.

I also have a corresponding terminfo file -- I don't use it on this
machine, but if anyone wants it I can mail or post it.
