Escape sequence for Function keys - terminfo

Having a doubt on how Function keys are mapped.
1. In my HPUX box my infocmp shows that kf1 (F1 key mapping) is not mapped. But somehow I am able to use an Informix form which requires navigation using F1 keys.

Code:
vt100-w|vt100-w-am|dec vt100 132 cols (w/advanced video),
        bce, bw, ccc, chts, cpix, crxm, da, daisy, db, eo,
        eslok, gn, hc, hls, hs, hz, in, km, lpix, mc5i, mir,
        msgr, ndscr, npc, nrrmc, nxon, os, sam, ul, xhp,
        xhpa, xon, xsb, xt, xvpa,
        cols#132, lines#24, vt#3,
        bel=^G, blink=\E[5m, bold=\E[1m, civis=\E[?25I,
        clear=\E[2J\E[H, cnorm=\E[?25h, cr=\r,
        csr=\E[%i%p1%d;%p2%dr, cub=\E[%p1%dD, cub1=\E[D,
        cud=\E[%p1%dB, cud1=\E[B, cuf=\E[%p1%dC, cuf1=\E[C,
        cup=\E[%i%p1%d;%p2%dH, cuu=\E[%p1%dA, cuu1=\E[A,
        cvvis=\E[?25h, dch=\E[%p1%dP, dch1=\E[1P,
        dl=\E[%p1%dM, dl1=\E[1M, ed=\E[0J, el=\E[0K,
        home=\E[1;1H, ht=\t, hts=\EH, il=\E[%p1%dL, il1=\E[1L,
        ind=\n, kbs=\177, kcub1=\EOD, kcud1=\EOB, kcuf1=\EOC,
        kcuu1=\EOA, knp=\E[U, kpp=\E[V, rc=\E8, rev=\E[7m,
        rmir=\E[4l, rmkx=\E[?1l, rmso=\E[m, rmul=\E[m,
        rs2=\E>\E[?3h\E[?4l\E[?5l\E[?8h, sc=\E7,
        sgr=\E[%?%p1%t;7%;%?%p2%t;4%;%?%p3%t;7%;%?%p4%t;5%;%?%p6%t;1%;m,
        sgr0=\E[0m, smir=\E[4h, smkx=\E[?1h, smso=\E[7m,
        smul=\E[4m, tbc=\E[3g,

2. My attempts to send F1 command to the form from a script has all failed (was able to send cursor down command cud1 etc):
Code:
    a. echo "^[Oa"  (verified that escape seq is Oa by using ^V)
     b. tput kf1

(obviously because kf1 is not mapped)

Had an interesting observation while I tee'd the stdin. Can add if needed. Please shed some light on how this works.

NAME
infotocap - convert a terminfo description into a termcap description SYNOPSIS
infotocap [-vn width] [-V] [-1] [-w width] file . . . DESCRIPTION
infotocap looks in each given text file for terminfo descriptions. For each terminfo description found, an equivalent termcap description is written to standard output. Terminfo use capabilities are translated directly to termcap tc capabilities. -v print out tracing information on standard error as the program runs. -V print out the version of the program in use on standard error and exit. -1 cause the fields to print out one to a line. Otherwise, the fields will be printed several to a line to a maximum width of 60 charac- ters. -w change the output to width characters. FILES
/usr/share/terminfo Compiled terminal description database. NOTES
This utility is actually a link to tic, running in -C mode. You can use other tic options such as -f and -x. SEE ALSO
