BS2 to BS2p

I'm having difficulty communicating between BS2 and BS2p.

BS2 uses:

Baud CON 813 '1200 bps, true, 8 bits
SEROUT DOUT, Baud, [noparse][[/noparse]Addr_Req, Data1, Data2, Data3, Data4, Data5,
Data6, Checksum]


BS2p uses:
Baud CON 2063 '1200 bps, true, 8 bits
SERIN DIN, Baud, [noparse][[/noparse]Addr_Req, Data1, Data2, Data3, Data4, Data5, Data6,
Checksum]

It is part of a RS485 network. There is no problem with the network,
because if I replace the BS2p with BS2, then all is fine.
When BS2p is used, then master cannot communicate with BS2p slave.

Does anyone have hints/tricks on communicating BS2 & 2p via
SERIN/SEROUT?

    Yellow,

    Just a guess, maybe try pacing the chars, the P is much faster than the 2.
