Re: [PATCH] Siemens SX1 kludge

Slave, what spec  are you reading ?

 From WAP-203-WSP-20000504, clause 8.4.2.1:

Constrained-encoding = Extension-Media | Short-integer
; This encoding is used for token values, which have no well-known 
binary encoding, or when
; the assigned number of the well-known encoding is small enough to fit 
into Short-integer.

Extension-media = *TEXT End-of-string
; This encoding is used for media values, which have no well-known 
binary encoding
