I ran into this too. Have a look at the register length after you have
tried to write to it. It was thought that in my case it was because I
was tunneling to the ROACH PC. Maybe it's more basic.

(read command which works)
result = send_rpc_katcl(l, 5000, KATCP_FLAG_FIRST |
KATCP_FLAG_STRING , "?write", KATCP_FLAG_STRING, regName,
KATCP_FLAG_STRING, "0", KATCP_FLAG_LAST|KATCP_FLAG_ULONG, 0,NULL);
(write command which fails quietly)
result = send_rpc_katcl(l, 5000, KATCP_FLAG_FIRST |
KATCP_FLAG_STRING , "?write", KATCP_FLAG_STRING, regName,
KATCP_FLAG_STRING, "0", KATCP_FLAG_LAST|KATCP_FLAG_ULONG, 0,NULL);
