[fa.telecom] info on racal vadic va212lc modem

meaders@KOREA-EMH.ARPA (10/14/85)

r-v's va212lc owner's manual leaves much to be desired.  there is
no mention of the pinout arrangement of the rs-232 i/o.  i have been able
to determine that the following pins are used (or at least connected):
2,3,5,6,,7,8,9,10,20,22.  can anyone tell me which does what & to whom?
tks.
